DNA is a nucleic acid that stores all the genetic information of an organism.
<em><u>DNA is a double stranded molecule and contains the nucleotide bases, Adenine, Guanine, Thymine, and Cytosine.</u></em>
<em><u>The DNA strand and its complementary strand are held together by hydrogen bonds between the base pairs on both stands. Guanine base on one strand is bonded to Cytosine base on the opposite strand. Adenine bonds or pairs with Thymine base on opposite strand.</u></em>
