Question

Which ribosomal site receives the incoming aminoacyl-tRNA during translation?

पर्याय

• The P site

• The D site

• The A site

• The E site

Answer 1

The A site (aminoacyl site) of the ribosome receives the incoming aminoacyl-tRNA. In this site, the anticodon of the tRNA pairs with the codon on mRNA. After peptide bond formation, the tRNA moves to the P site (peptidyl site), and the empty tRNA moves to the E site (exit site) before leaving the ribosome.
