Question

Describe the structure of RNA polynucleotide chain having four
different types of nucleotides

Mushtaq Ahmed · Accepted Answer

RNA is a single stranded nucleic acid It is a Polymer of ribonucleotides and
contains Uracil (U) instead of Thymine The four
nitrogenous bases present in RNA chain are– adenine, guanine,
cytosine and uracil

Nucleoside
= Nitrogenous base + Pentose sugar (linked through N
− glycosidic
bond)

Nucleotide
= Nucleoside + Phosphate group (linked through phosphodiester
bond)

Many
nucleotides link together through 3′ 
− 5′ 
phosphodiester bond to form polynucleotide chain of
RNA

In
course of formation of polynucleotide chain, a phosphate moiety
remains free at 5′ end of ribose sugar (5′ end of
polymer chain) and one -OH group remains free at 3′ end of
ribose (3′ end of polymer chain)
