The document discusses three stages of cell division in onion root tips: metaphase, anaphase, and telophase. Metaphase involves the alignment of chromosomes at the center of the cell. Anaphase is when the paired chromosomes separate and move to opposite poles of the cell. Telophase concludes cell division as the daughter nuclei and cells fully form.Difference between prokaryotic and eukaryotic transcription
Difference between prokaryotic and eukaryotic transcriptionAman Ullah
油
Prokaryotic and eukaryotic cells differ in their processes of transcription. Prokaryotes lack a nucleus and nucleolus, and their DNA is located in the cytoplasm. They have a single linear chromosome and use RNA polymerase to transcribe mRNA directly from DNA. Eukaryotes have a nucleus that houses their DNA, which is organized into linear chromosomes. They use RNA polymerase II to transcribe mRNA with introns that are later spliced out, producing mature mRNA ready for translation.Animal cell & tissue culture

Mammalian cell and tissue culture involves growing cells and tissues outside of their natural environment. There are several types of cell lines that can be cultured, including cancer cells, epithelial cells, and fibroblasts. Continuous cell lines can grow indefinitely, while normal cells have a finite lifespan. Primary cultures are established directly from tissue, while mass and clonal cultures allow isolation of specific cell types. Cells must be maintained in appropriate media, which often includes serum for growth factors. Tissues are typically dissociated using enzymes like trypsin or collagenase before culture. Cells can be cultured on surfaces like coverslips or in containers like flasks and test tubes. Regular medium changes are needed to sustain cultured cells and tissues.Actin, Myosin, and Cell Movement
Actin, Myosin, and Cell MovementAtai Rabby
油
Actin filaments, usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motora protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement. The most striking variety of such movement is muscle contraction, which has provided the model for understanding actin-myosin interactions and the motor activity of myosin molecules. However, interactions of actin and myosin are responsible not only for muscle contraction but also for a variety of movements of nonmuscle cells, including cell division, so these interactions play a central role in cell biology. Moreover, the actin cytoskeleton is responsible for the crawling movements of cells across a surface, which appear to be driven directly by actin polymerization as well as actin-myosin interactions.Post translational modification

This document discusses post-translational modifications (PTMs), which are enzymatic modifications of proteins after translation. It describes various types of PTMs like trimming, covalent attachments through phosphorylation, glycosylation, sulfation, methylation, and hydroxylation. The importance of PTMs in regulating protein function and cellular processes is highlighted. Detection methods for PTMs like mass spectrometry and fluorescent staining are also mentioned.Interferon
InterferonDr Chinmay Dash
油
Interferons (IFNs) are cytokines that were first recognized for their ability to interfere with viral infections. There are three main types of IFNs - alpha, beta, and gamma - which are classified based on their antigenicity and receptor binding. IFNs have diverse antiviral, immune enhancing, and antiproliferative properties. They work by binding to IFN receptors on cells and inducing the expression of interferon stimulated genes, which leads to an antiviral state. IFNs have many therapeutic applications for treating viral infections and cancers, though they can also cause side effects like fatigue, mood changes, and liver/blood abnormalities. Viruses have evolved various mechanisms to counteract the effects of IFNs.Mitosis powerpoint

Cell division through mitosis occurs in three main stages and produces two identical daughter cells. Mitosis includes prophase, metaphase, anaphase, and telophase where the genetic material is duplicated and separated. Cytokinesis then partitions the cytoplasm between the two daughter cells through cleavage in animal cells and cell plate formation in plant cells. Mitosis results in genetic identicalness and is important for growth, repair, and asexual reproduction.Cryopreservation and reconstitution of preserved cell lines

The lac operon controls the breakdown of lactose in E. coli bacteria. It consists of three structural genes (lacZ, lacY, lacA) that are regulated by a single promoter and operator region. In the absence of lactose, a lac repressor binds to the operator, preventing transcription of the structural genes. When lactose is present, it binds to the repressor and causes a conformational change, releasing it from the operator and allowing transcription. Mutations in the operator, structural genes, or promoter region provided insights into the operon's control mechanism.Maternal inheritance of chloroplasts dna

This document summarizes maternal inheritance of chloroplast DNA. It discusses how chloroplasts are inherited in the variegated four o' clock plant Mirabilis jalapa. Flowers on green branches produce only green offspring, while flowers on white branches produce only white offspring, demonstrating maternal inheritance of chloroplasts. Flowers on variegated branches produce offspring with mixed phenotypes, due to segregation of chloroplast types in the egg cell cytoplasm. This cytoplasmic inheritance demonstrates that in some plants, chloroplast DNA is inherited maternally rather than paternally.Regulation of gene expression b,pharm

Regulation of gene expression allows cells to control which genes are expressed and when. In prokaryotes like E. coli, genes are often organized into operons, clusters of genes that are co-transcribed. The lac and tryptophan operons are examples that are regulated by repressor proteins - the lac operon is induced by lactose binding to the repressor, while the tryptophan operon is derepressed in the absence of tryptophan. Eukaryotes like humans have more complex gene expression involving different cell types each expressing different gene sets.Mutation causing loss of cell cycle

This document discusses gene regulation in prokaryotes. It begins by defining gene expression and how genes control phenotypic traits through the proteins they encode. It then describes the basic components of genes and how they can be classified based on their expression. The main part of the document focuses on different mechanisms of transcriptional regulation in prokaryotes, including different types of operons (inducible, repressible), their components (promoter, regulator, operator genes), and mechanisms of regulation like attenuation and anti-termination. The key methods of gene regulation discussed are at the level of transcription initiation through repressors and activators binding to operator sites on DNA.2.

Polytene chromosomes are giant chromosomes that form in certain cell types through repeated rounds of DNA replication without cell division. This results in thousands of identical DNA strands aligned side by side. They are very large, up to 2000um long, and show characteristic banding patterns when stained. The bands correspond to regions of coiled DNA and contain genes, while interbands have less coiled DNA. Gene activity causes some bands to expand and puff out, indicating active transcription in those regions. Polytene chromosomes are useful for mapping genes and studying patterns of gene expression.Modern gene concept

Post-transcriptional modifications help process primary transcripts into mRNA in three main ways: 1) 5' capping protects the transcript and aids export from the nucleus, 2) Polyadenylation aids stability and transport, and 3) Splicing removes introns and ligates exons to form mature mRNA. In eukaryotes, this occurs in the nucleus and is essential for efficient translation. It can also result in alternative splicing to increase protein diversity from a single gene.Tryptophan
TryptophanPallaviShivankar1
油
The trp operon in E. coli bacteria encodes genes for the biosynthesis of the amino acid tryptophan. It is regulated by the trp repressor protein - when tryptophan levels are low, the repressor does not bind to the operator, allowing transcription of the operon; when tryptophan levels are high, it binds to the operator and blocks transcription, turning the operon off. This allows the bacteria to efficiently control tryptophan production depending on environmental availability.Standard Lymphocyte Culture

Peripheral blood contains lymphocytes that can be cultured in vitro using mitogens like phytohaemagglutinin to induce cell division. A standard 72-hour lymphocyte culture is initiated by adding whole blood to culture medium containing supplements and mitogens. Cells are harvested after 72 hours by adding a spindle inhibitor and subjecting them to hypotonic treatment and fixation to arrest cells in metaphase for analysis. Thymidine synchronization can be used to increase the proportion of cells in S-phase for a more synchronized cell division. Proper slide making and storage is required to produce high quality metaphase spreads for karyotyping.Transcription in prokaryotes

The document summarizes the lac operon in E. coli, which regulates the metabolism of lactose. The lac operon consists of structural genes (lacZYA) that encode enzymes for lactose catabolism, and control genes (promoter, operator, and repressor) that regulate expression. In the absence of lactose, the repressor binds the operator/promoter region, blocking transcription. In the presence of lactose or inducer molecules like IPTG, the repressor binds lactose instead, allowing transcription and expression of the structural genes. Glucose inhibits induction by lowering cellular cAMP levels needed for RNA polymerase binding to the promoter. The lac operon demonstrates negative and positive regulation of gene expression.Genetic Material

Histones are basic proteins found in eukaryotic cell nuclei that are responsible for DNA folding and chromatin formation. There are two main classes of histones: core histones and linker histones. Core histones include the H2A, H2B, H3, and H4 families, while linker histones include H1 and H5. Histone modification, including acetylation, methylation, and phosphorylation, can impact gene expression by altering the accessibility of DNA. Acetylation reduces the positive charge of histone tails, weakening their interaction with DNA and making it more accessible for transcription. Methylation and phosphorylation can also influence chromatin structure and cellular activity.Podcast category template.pptx brittany wuthrich (1) (3)

All land plants evolved from a single species of freshwater green algae that colonized land over 1 billion years ago. Early land plants like bryophytes and non-vascular plants developed adaptations like an alternation of generations lifecycle and protective structures to survive on land. Vascular plants then evolved xylem and phloem tissues for transport which allowed them to grow larger. Seed plants later evolved seeds for protection and dispersal.Bio 221 2

Mitosis is the process of cell division that results in two daughter cells having the same number and type of chromosomes as the parent nucleus. It produces genetically identical cells in both animals and plants. The main stages of mitosis are prophase, prometaphase, metaphase, anaphase and telophase. During prophase, the chromatin condenses into chromosomes. In metaphase, the chromosomes align along the metaphase plate. In anaphase, the sister chromatids are separated and moved toward opposite poles. Telophase involves the reformation of the nuclei around the separated chromosomes. Cytokinesis then divides the cytoplasm, completing cell division.

This document discusses sexual reproduction in flowering plants. It describes the structures and processes of microsporogenesis and megasporogenesis, which produce microspores and megaspores through meiosis. The microspores develop into pollen grains, and the megaspore develops into the embryo sac. Fertilization occurs when a pollen tube delivers sperm to the embryo sac, resulting in the fusion of gametes and formation of a zygote. The document contrasts the differences between microsporogenesis and megasporogenesis, and discusses self-incompatibility and techniques like emasculation and bagging used to facilitate controlled pollination.Cbse class 11 biology labelled slides

Blind Spots in AI and Formulation Science Knowledge Pyramid (Updated Perspect...Ajaz Hussain

This presentation delves into the systemic blind spots within pharmaceutical science and regulatory systems, emphasizing the significance of "inactive ingredients" and their influence on therapeutic equivalence. These blind spots, indicative of normalized systemic failures, go beyond mere chance occurrences and are ingrained deeply enough to compromise decision-making processes and erode trust.
Historical instances like the 1938 FD&C Act and the Generic Drug Scandals underscore how crisis-triggered reforms often fail to address the fundamental issues, perpetuating inefficiencies and hazards.
The narrative advocates a shift from reactive crisis management to proactive, adaptable systems prioritizing continuous enhancement. Key hurdles involve challenging outdated assumptions regarding bioavailability, inadequately funded research ventures, and the impact of vague language in regulatory frameworks.
The rise of large language models (LLMs) presents promising solutions, albeit with accompanying risks necessitating thorough validation and seamless integration.
Tackling these blind spots demands a holistic approach, embracing adaptive learning and a steadfast commitment to self-improvement. By nurturing curiosity, refining regulatory terminology, and judiciously harnessing new technologies, the pharmaceutical sector can progress towards better public health service delivery and ensure the safety, efficacy, and real-world impact of drug products.Rass MELAI : an Internet MELA Quiz Prelims - El Dorado 2025
