What is the purpose of the peptidyl transferase function in ribosomes? Glutamine

Question

What is the purpose of the peptidyl transferase function in ribosomes? Glutamine is coded for by just two codons, CAA and CAG. The best explanation as to how this degeneracy occurs is: This represents a gene of a The start of translation codon is identified in region The consensus sequence in region codes for the binding of the ribosome in the mRNA. The promoter is in region The stop codon is identified in region A mutation in region 8 would be expected to: Which of the following scientists is associated with the operon theory of gene regulation? A mutant E.coli strain always produces high amounts of beta-galactosidase. What is a possible genotype of the mutant cells? Which of the following merodiploids is inducible for genes Z, Y, and A with the addition of lactose?

Explanation / Answer

33. it forms peptide bonds

34. wobble in the 5' position of the anticodon allows a single tRNA to bind to both codons.

35. prokaryote. Its polycistronic .

37. 1

38. 2. Promotor sequence is specified by TATATA sequence.

39. 8 .

40. e. Mutation in terminator sequence will disrupt translation termination.

41. e

42. d. The gene for inducer is mutated(I-), hence there is no production of regulator protein and all genes are (+). So there will be continuous expression of Beta- galactosidase.
