Rosalind Franklin was a British scientist who played a major role in discovering the structure of DNA in the 1950s. She discovered that DNA had a helical structure, but did not receive the Nobel Prize for the discovery as her colleagues did. Franklin's contributions to the discovery of DNA were overlooked for many years because of gender bias in the scientific community at the time. She died in 1958 at the age of 37 before her work was fully recognized.

Rosalind Franklin was a British biophysicist and X-ray crystallographer who made several important contributions to the understanding of DNA structure. She discovered that DNA could crystallize into two different forms, A and B, and developed techniques to separate these forms. Her most important contribution was using X-ray diffraction images to show that DNA has a double helix structure. If not for her early death from cancer, she likely would have received a Nobel Prize for her work determining the structure of DNA.Discovery dna

The document summarizes the history of discoveries leading to the understanding that DNA is the molecule of heredity. It describes early experiments in the 1900s and 1920s by scientists like Griffith who found that traits could be transferred between bacteria. Further work by Avery in 1944 found that DNA was responsible for this transformation. Chargaff discovered proportional relationships between DNA bases within species. Experiments in the 1950s by Hershey and Chase and the work of Franklin, Wilkins, Watson and Crick ultimately revealed DNA's double helix structure and its role in storing and transmitting genetic information from parents to offspring.Priestley & lavoisier 112

This document provides a summary of Antoine Lavoisier's contributions to chemistry, including:
1) Lavoisier disproved the theory of phlogiston through experiments showing that combustion reactions involve gases combining with oxygen rather than releasing phlogiston.
2) He established that water is a compound of hydrogen and oxygen by collecting and weighing the products of a combustion reaction.
3) Lavoisier is considered the founder of modern chemistry for his establishment of a system of chemical nomenclature and for listing the first table of chemical elements. He emphasized quantitative experiments and conservation of mass.A complete PPT on DNA

The discovery of the DNA double helix structure in 1953 by James Watson and Francis Crick was one of the greatest scientific achievements of the 20th century. They were able to determine that DNA consists of two strands coiled around each other to form a double helix. Each strand is made up of a backbone of alternating sugar and phosphate groups with nitrogenous bases protruding from the sugars. The bases on one strand form hydrogen bonds with complementary bases on the other strand. Watson and Crick's double helix model explained how DNA could replicate itself and be stable within organisms. Their discovery fundamentally changed our understanding of genetics and laid the foundation for modern molecular biology and genetic engineering.The Discovery of DNA

Rosalind Franklin was an expert in using X-ray crystallography techniques to study DNA structure. Her clear images of DNA, including photograph 51, provided essential information about DNA's structure. Crick and Watson obtained Franklin's data from Wilkins and used it to confirm their ideas about DNA's double-helix structure. Though her work was instrumental in the discovery, Franklin was not recognized at the time since Watson's memoir disparaged her and she had died before the 1962 Nobel Prize was awarded to Crick, Watson, and Wilkins for discovering the structure of DNA.SPECIES-SPECIATION.pptx

The biological species concept defines a species as a group of organisms that can interbreed and produce fertile offspring. Reproductive isolation prevents different species from successfully interbreeding, through prezygotic barriers like habitat isolation that prevent mating, and postzygotic barriers where hybrid offspring are infertile. Speciation, the formation of new species, occurs through geographic isolation of populations (allopatric speciation) or evolution of reproductive barriers without separation (sympatric speciation).Charles Darwin

1) Charles Darwin was a British naturalist born in 1809 who studied medicine and divinity before joining a scientific expedition on the HMS Beagle as their geologist from 1831-1836.
2) While traveling on the Beagle, Darwin was influenced by the ideas of Charles Lyell and observed unique species of finches on the Galapagos Islands, sparking his theory of evolution by natural selection.
3) After corresponding with Alfred Russel Wallace, Darwin published On the Origin of Species in 1859, introducing his theory that organisms change over generations through a process of natural selection, survival of the fittest, and gradual speciation from common ancestors.Albert einstein english

Albert Einstein was born in 1879 in Germany to a middle-class Jewish family. As a child, he was fascinated by invisible forces after encountering a compass at age 5. He mastered higher mathematics by age 16. He studied at the Higher Technical School in Zurich, graduating in 1900. After graduation, Einstein worked in a patent office in Bern, Switzerland. In 1905, he published four groundbreaking papers, one establishing the photoelectric effect and the famous equation E=mc2. Einstein is renowned for his theories of special and general relativity. He won the Nobel Prize in Physics in 1921 for his services to theoretical physics and especially for his discovery of the law of the photoelectric effect.

Albert Einstein was born in Germany in 1879 and showed an early interest in science after being impressed by a compass as a child. He developed his Special Theory of Relativity in 1905 while working as a patent clerk, which established that the laws of physics are the same in all frames of reference moving at a constant speed. This theory disrupted Newtonian concepts of space and time and introduced mass-energy equivalence with the iconic E=mc2 equation. Einstein subsequently developed his general theory of relativity and made numerous other significant contributions to physics, while also escaping Nazi Germany in the 1930s and settling in the United States.DNA discovery & Structure 8.1 & 8.2

This document summarizes several principles of Mendel's laws of inheritance:
1. Mendel conducted hybridization experiments on peas from 1856-1863 and proposed the basic laws of inheritance in organisms.
2. Inheritance follows patterns of dominance, with one allele expressing itself over the other in a gene pair. Mendel also described the law of segregation where alleles do not blend but are recovered unchanged in subsequent generations.
3. The principle of independent assortment holds that different genes independently separate from one another during the formation of reproductive cells, as Mendel first observed in his pea plant experiments.Genetic drift
Genetic driftChithra S
油
Genetic drift is a mechanism of evolution responsible for random changes in a gene pool through chance changes in allele frequencies in populations over time. It tends to have a stronger effect in smaller populations and can reduce genetic variation through allele losses. There are two types of genetic drift: bottleneck effect, which occurs after disasters reduce population size, and founder effect, which happens when new colonies are formed through migration.GREGOR JOHANN 2 MENDEL.

Gregor Johann Mendel was an Augustinian monk who conducted genetic experiments with pea plants in the 1850s and 1860s. He presented his findings in 1865, which proposed basic principles of inheritance now known as Mendel's laws of inheritance. However, his work was not widely recognized until the 1900s. Mendel's experiments involved breeding thousands of pea plants and tracking discrete traits like flower color, seed texture, and pod shape over multiple generations. His results showed dominant and recessive traits are inherited in predictable ratios and segregate independently of one another. Mendel's experiments were groundbreaking in establishing genetics as a science.History of molecular genetics vruddhi

Genetic drift is a mechanism of evolution that causes changes in allele frequencies through random chance events rather than natural selection. It is most prominent in small populations where random fluctuations can have large effects. Two types of genetic drift are the bottleneck effect, which occurs when a population is severely reduced in size, and the founder effect, which occurs when a new population is established by a small number of individuals from a larger population. Both types can result in the loss of genetic variation within populations.Open stax biology (nonmajors) ch13

Charles Darwin developed the theory of evolution by natural selection based on observations he made during a 5-year voyage on the HMS Beagle. His theory proposed that all species share a common ancestor and evolve over time through gradual processes of variation, competition for limited resources, and natural selection of beneficial traits. Key evidence came from studies of finches and tortoises on the Galapagos Islands which had adapted in different ways on different islands. Darwin's theory revolutionized scientific understanding of the diversity and relatedness of life on Earth.Discovering DNA Timeline

- Women were denied access to universities until the late 19th century in many countries. The first women's colleges were established in the mid-19th century.
- Figures like Rosalind Franklin, Marie Curie, and Emily Davis helped pave the way for women in scientific fields through their groundbreaking research despite facing discrimination.
- During World War II and the Cold War era, more women entered scientific fields as attitudes gradually changed. However, discrimination continued and women had to prove their work was equally valid as men's.

- Franklin faced challenges as a female scientist in the 1950s, with accounts describing her in gendered or diminishing terms. The language used to describe women in science has evolved since.

Vincent van Gogh was a post-Impressionist painter born in 1853 who suffered from depression. He only sold one painting during his lifetime but is now considered one of the most famous and influential artists of all time. Some of his most famous works include The Starry Night and Sunflowers. He committed suicide in 1890 at the age of 37 by shooting himself, though it is believed this may have been a cry for help rather than a genuine suicide attempt. Throughout his life, van Gogh was supported by his brother Theo, an art dealer, who sold some of van Gogh's paintings after his death to provide for his sisters.Egyptian mummies

The ancient Egyptians developed the practice of mummification to preserve the human body after death, which they believed was essential for an afterlife. The complicated mummification process took around 70 days and involved removing internal organs, dehydrating the body with natron, and wrapping it in linen bandages. They also buried the dead with objects from their lives. Wealthy Egyptians could afford burial in tombs, while poor Egyptians were buried in the sand. Mummies and pyramids were ways to protect the body into the afterlife.Protein is a life molecule

The document summarizes information about proteins including their structure, functions, daily requirements, and types. It discusses how proteins are composed of amino acids and form complex structures within cells. The main points are:
- Proteins are composed of chains of amino acids and perform critical functions within cells like building, catalyzing reactions, signaling, transporting materials, and providing defenses.
- Protein structure involves primary, secondary, tertiary, and sometimes quaternary levels that give proteins their shape and determine their specific roles.
- Essential proteins must be obtained through diet as the body cannot synthesize all amino acids. Complete proteins contain all essential amino acids while incomplete proteins require combination with other foods.

Rosalind Franklin
- 1. Presentation BY: SESILI P. 11th grade Student Chkhoria public school GEORGIA Rosalind Franklin
- 2. 2 Rosalind Franklin is a scientist who played a major role in the discovery of DNA, although her contributions were neglected for many years because this field (like many other fields) was dominated by men.
- 3. 3 Rosalind Franklin discovered the helix of the structure of DNA, although the Nobel Prize went to her colleagues for this discovery. Those who, after removing Rosalind from the lab, used her calculations. Franklin never heard of it because he died four years before the triumph of his colleagues.
- 4. 4 Rosalind Franklin died in 1958 at the age of 37 without receiving the recognition she deserved for her most important scientific discovery. She died, and the secret in the scientific community was only revealed in 1975.
