Nucleic acids exhibit secondary structure. Describe through Watson Crick Model.

Answers (1)

It is known that DNA and RNA exist in the form of a helix. Since a long chain of polymer is arranged as a helix. And a helix is called secondary structure. RNA forms a single-stranded helical form while DNA forms a double helix. It is known that helix is regarded as a secondary structure; thus, in secondary structure, nucleic acids exist.

Arranged in a double helix, two polypeptide chains make up the DNA. Nitrogenous bases are present towards the inner side in the DNA while the backbone is made up of sugar-phosphate. The nitrogenous bases connect with each other through H bonds.This H bond provides stability to the helix.
