DNA is chemically made up of Deoxyribose sugar , Nitrogenous bases (Adenine, Guannine, Cytosine & Thymine) and Phosphate.The backbone of the DNA strand is made from alternating phosphate and sugar residues.The sugar in DNA is the pentose (five carbon) sugar 2-deoxyribose. The sugars are joined together by phosphate groups that forms phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings.
DNA replication is semi-conservative. It is enzyme driven process in which a new copy of DNA is formed having half portion contributed by the previous DNA and another half formed by complimentary base pairing.
