7. How are peptide bonds formed between amino acids in the elongation process of the translation of mRNA? The amine group of one amino acid reacts with amine group of another amino acid.
The carboxyl group of one amino acid reacts with amino group of the same amino acid.
The amine group of one amino acid reacts with carboxyl group of another amino acid.
The carboxyl group of one amino acid reacts with carboxyl group of another amino acid.

The correct answer is - The amine group of one amino acid reacts with the carboxyl group of another amino acid.

Explanation:

At the point when two amino acids combine and the carboxyl group of the first amino acid responds with the amino group of the neighboring amino acid, the final result of this mix is A di-peptide and water.  

The connecting of two amino acids is joined by removal of a water molecule. Peptide bonds are framed by a biochemical response that removes a water atom as it joins the amino group of one amino acid to the carboxyl group of a another amino acid. The linear sequence of amino acids inside a protein is viewed as the essential structure of the protein.

Thus, the correct answer is - The amine group of one amino acid reacts with the carboxyl group of another amino acid.
