During Elongation,which Site in the Ribosome Represents the Location Where

Question

During elongation,which site in the ribosome represents the location where a codon is being read?
A)E site
B)P site
C)A site
D)the small ribosomal subunit
E)exit site

Accepted Answer

The A site is the site in the ribosome where the incoming aminoacyl-tRNA binds and the codon on the mRNA is read during elongation. The P site holds the tRNA that carries the growing polypeptide chain, while the E site is the exit site for the spent tRNA. The small ribosomal subunit is involved in the initiation of translation.
