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) A siteB) P site
C) E site
D) exit tunnel
E) directly to the cytosol
Answer: C
Which component of the complex described enters the exit tunnel through the large subunit of the ribosome?
A) tRNA with attached lysine (#1)B) tRNA with polypeptide (#2)
C) tRNA that no longer has attached amino acid
D) newly formed polypeptide
E) initiation and elongation factors
Answer: D
