Explanation of Solution

DNA acts as information storage molecules. It stores genetic information in its chemical structure. It stores genetic information in order of its nucleotide bases. There are four types of nucleotide bases in DNA, namely Adenine, Thymine, Guanine and cytosine.

The nucleotide bases arranged in a specific order essentially stores all the information that is required for a cell to sustain.

The nucleotide bases arranged in a specific order dictate the synthesis of proteins and thereby help in functioning of cells.
