Question

After the Ef-G cycle the A site_________

(a) Houses peptide bound tRNA

(b) Amino acid bound tRNA

(c) Empty

(d) Uncharged trNA

I got this question in an interview for internship.

I'd like to ask this question from Elongation and Termination topic in chapter Gene Expression : Translation of Cytogenetics

Answer 1

The correct option is (c) Empty

To elaborate: The EF-G factor helps in translocation of the ribosome such that the peptide bound tRNA shifts to the P site and A site becomes empty and available to bind another charged tRNA.
