The document summarizes the process of protein synthesis. RNA polymerase in the nucleus unwinds DNA and makes mRNA using the DNA as a template. The mRNA then exits the nucleus through the nuclear pore and enters the cytoplasm. In the cytoplasm, rRNA attaches to ribosomes and the start codon of the mRNA. tRNA then brings amino acids to the ribosome based on the mRNA codons to assemble the protein chain. The ribosome moves along the mRNA, adding more amino acids until protein synthesis is complete.Bioproject2

The document describes the process of protein synthesis, which has two main steps: transcription and translation. During transcription, RNA polymerase binds to DNA and builds an mRNA strand using the coding region as a template, before the mRNA strand exits the nucleus. Translation then occurs on ribosomes, where tRNAs bring amino acids to the mRNA start codon and assemble a protein based on the mRNA sequence until reaching the stop codon.Dna flipbook

Transcription occurs in the nucleus and involves RNA polymerase unwinding DNA and reading its base pairs to produce mRNA. The mRNA then exits the nucleus. Translation occurs in the cytoplasm, where ribosomes use the mRNA to assemble amino acids brought by tRNAs into a protein chain. tRNAs check for mistakes and bind amino acids to the growing protein via peptide bonds until a stop codon signals completion.Transcription and Translation Flipbook

Gregor Mendel was an Austrian monk who is considered the father of genetics. He conducted experiments with pea plants in which he studied 7 different traits. Through his experiments, Mendel discovered the principles of heredity, including that traits are passed from parents to offspring through discrete units called genes, and that some genes are dominant while others are recessive. When Mendel crossed plants with different traits, he found that the offspring expressed the traits of only one parent, not a blend, and that recessive traits could reappear in later generations. This led Mendel to propose that genes segregate and assort independently during the formation of gametes.Protein synthesis trenton stouffer

DNA replication begins at the origin of replication where DNA helicase unwinds and unzips the double helix. DNA polymerase reads the bases on one strand and adds complementary bases to the other strand. The leading strand is replicated continuously while the lagging strand is replicated discontinuously in fragments called Okazaki fragments. DNA primase adds primers to fill in the lagging strand, and DNA ligase seals the fragments together with phosphodiester bonds.Mine all mine

The process of transcription begins in the cell nucleus, where RNA polymerase breaks apart DNA and uses it as a template to create mRNA strands. During this process, thymine is replaced with uracil to form RNA. The mRNA strand then exits the nucleus through a nuclear pore. Translation occurs in the cytoplasm, where the mRNA is read by ribosomes in groups of three codons. Transfer RNA molecules bring amino acids to the ribosome based on codon-anticodon base pairing. As the ribosome moves along the mRNA, the growing polypeptide chain is released once a stop codon is reached.Ad

- 44. Protein
- 45. Explanation Transcription 1.After DNA is unwound by helicase, it is unzipped by RNA polymerase 2. The polymerase reads the DNA from the promoter, to the coding region, until it hits the termination sequence. 3. The polymerase is able to make a complementary set of bases, except uracil is used to match with adenine instead of thymine. 4. The polymerase then completes a strand of mRNA by making the sugar and phosphate back bone. (Includes start and stop codon) 5. The mRNA leaves the nucleus through the nuclear pore, and heads into the cytoplasm.
- 46. Explanation Translation 1.When in the cytoplasm, the mRNA heads for the rRNA, or ribosome. 2. The ribosome reads the mRNA from the start codon to the stop codon. 3. The rRNA sends for tRNA with anti-codons that match each codon. 4. The matching anti-codons attach to their complementary bases, forming amino acids and peptide bonds between them. 5. The amino acids bend and twist together to form a completed protein.
