Question

The diagram shows one step in the process of protein synthesis. mc015-1.jpg What is the purpose of the peptide bond that is shown in the diagram? It connects amino acids. It connects ribosomes. It connects tRNA. It connects anticodons.

Answer 1

Connects amino acids

Answer 2

The right answer is It connects amino acids.

• Amino acids are the building blocks of proteins.

• There are 21 amino acids, but only one type of binding used to connect them: it is the peptide bond.

The peptide bond is formed during the translation step by a covalent bond between an α-amino group of an amino acid and the carboxylic group of another amino acid. A molecule of water is eliminated.
