An Intiative by Sri Chaitanya

It is made up of two polynucleotide chains, where the backbone is constituted by nitrogen bases.

The two chains are coiled in a left handed fashion in B-DNA.

The plane of one base pair stacks over the other in double helix. This, in addition to H-bonds, confirms stability of the helical structure.

It is made up of four type of nucleotides, these are deoxyadenosine, deoxyguanosine, deoxycytidine and deoxythymidine.

Detailed Solution

The backbone of a polynucleotide chain is formed due to sugar and phosphates. The nitrogenous bases linked to sugar moiety project from the backbone. The two chains of B-DNA are coiled in a right-handed fashion. The plane of one base pair stacks over the other in double helix. This, in addition to H-bonds, confers stability of the helical structure. Examples of nucleosides include deoxycytidine, deoxyguanosine, deoxythymidine, and deoxyadenosine.
