Question

what purpose does the peptide bond serve in protein synthesis?

• it connects amino acids.
• it adds a water molecule to the amino acid chain.
• it releases the protein from the trna.
• it makes a strand of mrna.

Explanation:

During protein synthesis, amino acids are linked together sequentially. A peptide bond is a covalent bond that forms between the carboxyl group of one amino acid and the amino group of the next, creating the polypeptide chain that folds into a protein. The other options are incorrect: peptide bond formation releases water (does not add it), proteins are not released from DNA directly, and mRNA is made via transcription not peptide bonds.

Answer:

A. It connects amino acids.
