Agenda: Notes on DNA Structure of DNA worksheet No homework! CHAPTER 10: DNA,RNA & Protein Synthesis So - What is DNA?. The number of codons on an mRNA strand would depend on the protein for which the mRNA strand is coded for and there are no set amount or average amount. It includes three steps: initiation, elongation, and termination. DNA code of a gene is first converted into mRNA ( messenger RNA) through a process called transcription ( occurs in nucleus of eukaryotes and cytoplasm of prokaryotes). Skills FocusUse Models, SequencePre-Lab Questions 1. tRNA is the fetching puppy. Step 2 of Protein Synthesis TRANSLATION This is when Protein Synthesis actually occurs using the mRNA made in Transcription Messenger RNA moves to the cytoplasm and attaches to ribosome: (site of protein synthesis) At the ribosome, tRNA (transfer RNA) brings an amino acid to match the codons of the mRNA sequence. What will most likely happen if there is a change in the base sequence of this molecule? a. Like the period at the end of the sentence, these codons tell the cell when to stop translating mRNA. Answer Reverse transcriptase 27 Why codons are redundant? Answer Codons are redundant because, single amino acid can be coded by two or three codons.

The ribosome serves as the site and carries the enzymes necessary for protein synthesis. Because the kind of amino acid attached to a tRNA depends on the tRNA’s anticodon, the base pairing between the anticodons and codons brings a specific sequence of amino acids to the ribosomes. Answer and Explanation: During protein synthesis, DNA is first transcribed to form mRNA in the nucleus. That produces some redundancy in the code: most of the amino acids being encoded by more than one codon. Practice using the dictionary of the genetic code in your textbook. The AUG codon then base-pairs with the anticodon of tRNA carrying methionine. It occurs in the nucleus. Get it here. During translation ribosomes read the mRNA code and tRNA brings.
