Q5. What is DNA?
DNA is Deoxyribonucleic Acid. This is the amazing long double-sprial molecule that is found inside every living cell. it is made up of long chains of sugars and phosphates linked by pairs of chemical ‘bases’-adenine, cytosine, guanine and thymine. the order in which these bases recur provides in code form the instructions for all the cell’s activities, and for the lifeplan of the entire organism.
