Question

explain the double helix structure of DNA with labelled digarm​

Answer 1

here is your answer dear

A DNA double helix consists of two spiral chains of deoxyribonucleic acid. The shape is similar to that of a spiral staircase. DNA is a nucleic acid composed of nitrogenous bases (adenine, cytosine, guanine, and thymine), a five-carbon sugar (deoxyribose), and phosphate molecules.

Answer 2

DNA has a double-stranded helical structure.It is also known as B form of DNA. It is made up of nitrogenous base, deoxyribose sugar, and phosphate. The nitrogenous base, deoxyribose sugar, and phosphate link together forms the nucleotide chain.
