Bio 212 discussion homework 9-Saved to my Mac ut References Mailings Review View No SpacingHeading1 Headis 1) Identify the following mutations: (mention-in terms of amino acid change-missense/nonsense/silent] a) CCU to CCG b) UGC to UGA c) GAA to GUA Anticodon CAI can pair with how many codons? (mention all possible codon sequences) 2) 3) Following tRNA are given associated with their respective amino acids. On which ribosomal site (A/P/E) do they attach to? N-Formylmethieninsehionne 4) Write the 4 steps of translation termination. Where does the energy comes from for the following events during translation? a) 5) movement of tRNAs into the ribosome sites b) used to make the peptide bond MacBookExplanation / Answer
1.A. CCU TO CCG PRO TO PRO SILENT
B. UGC TO UGA CYS TO STOP NONSENSE
C. GAA TO GUA GLU TO VAL MISSENSE
2. THREE A,U,C
3. N-Formylmethionine - P site
Methionine - A site
4. 1. It reach one of three termination codons in the mRNA (UAA, UAG, UGA)
2.hydrolysis of the terminal peptidyltRNA bond
3. release of the free polypeptide and the last tRNA, now uncharged, from the P site
4. dissociation of the 70S ribosome into its 30S and 50S subunits.
5. Movement of the ribosome along the mRNA requires EF-G and the energy provided by hydrolysis of GTP.
