Formation of the Peptide Bond Could Be Described As

Question

Formation of the peptide bond could be described as:
A)a spontaneous reaction between two peptides,forming a covalent bond.
B)a ribosome-catalyzed process occurring in the nucleus.
C)a tRNA catalyzed process.
D)a ribosome-catalyzed dehydration reaction (H20 released).
E)transcription,a key process in gene expression.

Accepted Answer

Formation of the peptide bond involves a dehydration reaction, where a molecule of water is released from the amino group of one amino acid and the carboxyl group of another amino acid in the presence of a ribosome, resulting in the formation of a covalent peptide bond. This process is catalyzed by the ribosome and is known as ribosome-catalyzed dehydration reaction.
