Summary Introduction

To review:

The diagram of a phosphodiester linkage in B-DNA, in association with water molecules.

Introduction:

The B-DNA is the physiological form that consists of two polydeoxynucleotide strands thatwind around each other in a right-handed double helix. The DNA have a nitrogenous base (either purine or pyrimidine) attached to the first carbon of deoxyribose sugar. There is a 3’-5’ phosphodiester linkage between two nucleotides in the strand. Each phosphate group can form hydrogen bonds with six water molecules.
