Summary Introduction

To label: The components of the polynucleotide chain.

Introduction:

Polynucleotide chain consists of a chain of nucleotide units. Refer to Fig. 5.24 (a), “Components of nucleic acids” in the textbook. Each nucleotide consists of a pentose sugar, phosphate group, and a nitrogenous base. In a polynucleotide chain, phosphate group joins the sugars of two nucleotides by phosphodiester bonds.
