During the Elongation Step of Translation,____

Question

During the elongation step of translation,____.
A) the small ribosomal subunit pairs with an anticodon
B) amino acids are added to a growing polypeptide chain
C) methionine is inserted at the beginning of all proteins
D) mRNA is transformed into tRNA
E) release factors bind to stop codons

Accepted Answer

During the elongation step of translation, amino acids are added to the growing polypeptide chain. This occurs as the ribosome moves along the mRNA strand, using the codons to attract tRNAs bearing the appropriate amino acids. The amino acids are then linked together by peptide bonds, gradually forming the polypeptide chain.
