Question

A transfer RNA (#1) attached to the amino acid lysine enters the ribosome. The lysine binds to the growing polypeptide on the other tRNA (#2) in the ribosome already.

Where does tRNA #2 move to after this bonding of lysine to the polypeptide?

A. P site
B. A site
C. E site
D. directly to the cytosol
E. exit tunnel

Answer 1

Answer: E-site

Step-by-step explanation:

The exit site (E-site) is the third and final binding site during protein synthesis. After attachment to the aminoacyle (A-site) or peptidyle (P-site) as in the case, tRNA moves to the exit site.
