Question

STEP 1 HN-1 (8 pts) The figure at the right shows the stage in translation when an incoming aminoacyl-tRNA has bound to the A-site on the ribosome (step 1). Using the same shapes for the tRNAs and amino acids shown in Figure A as a guide, show on Figures B and C what happens in the next two steps. Step 2 represents the peptidyl transferase reaction inherent to the large ribosomal subunit. In step 2 indicate the new peptide bond that connects amino acids 3 and 4 and where tRNAs #3 and 4 are located). At step 3 the EF-G dependent translocation of the small subunit on the mRNA has taken place (indicate the positions of tRNAs #3, 4 and the next aminoacyl tRNA, #5). (B) STEP 2 (C) STEP 3 I have drawn the chemical structures at step 1 and I would like you to show the nucleophilic attack that creates the peptide bond connecting amino acids 3 and 4. Please continue my figure by showing the structures after this peptidyl transferase reaction H Ry N-C-H I-2 HY не tRNAC ERNAH

Answer 1

Ans: II Please Give Ratings II

Your required diagram of stages 1,2,3 and the neucliophilic attack are as follow;

(A) STEP11 0 ERNA (B) STEP2) New peptide bord TIL STEP3 R5 0-2---- HO
