Answer to Question #93276 in Genetics for Nour fahes

Question

1- Consider a peptide of 30 amino acids. How many rounds of elongation were there during the translation?
a- 30 b-10 c-29 d-28 cycles
2- the open reading frame of the mRNA consists then of: (for the given above)
a-29 sense codons b-30 sense codons c-31 sense codons d-29 codons

Answer 1

During translation initiator t-RNA attaches to p -site . During elongation phase remaining aminoacids reach the ribosomes .In the last phase termination stop codons will not represent any aminoacid.

1. In the given question peptide has 30 aminoacids so there will be 29 elongation rounds

2. There are 30 aminoacids means 30 sense codons.
