Homework Answers
Option c. During elongation preloaded tRNA enters the ribosome A site.
Ribosome has 3 binding sites- A, P and E (Therefore, ruling out option 2). At A site, the incoming preloaded tRNA (amino-acyl tRNA) enters and binds with the codon of the ribosome. The tRNA carrying the growing polypeptide chain is then translocated to the P site , whereas the E site carries the empty tRNA before it leaves the ribosome.
Therefore the correct option is C.
