Question

Double helic structure dna explain the structure

Answer 1

In 1953 Watson and Crick discovered DNA. A double helix structure is a combination of 2 strands which divide to more more strands. A double helix structure consist of Pentose sugar, Nitrogenous bases, Hydrogen bond. The bases are of 4 types- Adenine(A),Guanine(G),Thymine(T),Cytosine(C). These bases make bond with each other in different combinations like AC,GA,TC,TA etc. These different variations create difference between each individuals blood.
