DNA Explanation:

DNA stands for Deoxyribonucleic acid. A DNA molecule usually carries genetic information in an organism. It is carried in the nucleus of eukaryotic organisms and sometimes just forms a mass in the cytoplasm like in case of prokaryotes. It is formed by two chains that coil around each other and form an alpha helix structure. It codes information for all the structural and functional activities of an organism.

DNA Explanation:

Deoxyribonucleic acid is a molecule that is made up of two chains that coil around each other to form an alpha helix structure. DNA carries the genetic information that is coded for all the body functions including growth, functioning and reproduction. It contains both coding and non coding sequences.
