<h3><u>Explanation;</u></h3>
<em><u>DNA, known as deoxyribonucleic acid is a type of nucleic acid which is important to all living organisms as it helps store genetic information.</u></em>
<em><u>All living organisms store their genetic information using DNA molecules or RNA molecules. Most organisms contains DNA that have similar components, however their DNA will differ in number and also the sequences. </u></em>
<em><u>The similarity between the molecules of DNA indicates a common ancestry among organisms. </u></em>
