During translation, the amino acyl t-RNA complex attaches to small ribosomal unit at
Correct answer: D. A site
- A. P site
- B. E site
- C. mRNA
- D. A site
Explanation
During translation, the aminoacyl-tRNA complex attaches to the small ribosomal subunit at the A site (Answer D) of the ribosome. The A site (aminoacyl site) is where incoming aminoacyl-tRNA molecules, carrying the next amino acid in the polypeptide chain, bind to the ribosome.
