Question

polynucleotide chain of dna

Answer 1

DNA is a hereditary material found in all the living organisms except some ciruses.

DNA having double helix structure, having two polynucleotide chains running in different directions. One is 5'-3',. and another one is 3'-5'.

There are purine and pyrimidines that are bond together.

Mainly Adenine(A) , Guanine(G), Cytosine (C), Thymine(T).

Adenine always forms two weak hydrogen bonds with the Thymine.

Guanine always forms three weak hydrogen bonds with cytosine.

Hope it will be useful for you.

All the best

Answer 2

Answer:

Each polynucleotide chain consists of a string of nucleotides linked by phosphodiester bonds.
