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.

Answer 1

I believe the peptide bond connects amino acids because the chain of amino acids that is formed is also called a peptide. 

Answer 2

The correct answer is option A

The purpose of peptide bond is to connect the amino acids. The amino acids are connected together by the the bond known as peptide bond.

A peptide bond is formed between two molecules one is amino group and other one is a carboxyl group which is accompanied by the release of a water molecule.

This is a dehydration synthesis kind of a reaction.
