Question

Quizplus · Accepted Answer

The A, P, and E sites are part of the large ribosomal subunit, where amino acids are assembled into a polypeptide chain during translation. DNA, mRNA, tRNA, and the spliceosome are involved in other steps of gene expression but not directly involved in polypeptide synthesis.
