Question

which are the components of DNA molecule​

Answer 1

Answer:

DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.

DNA is the abbreviated form of Deoxyribonucleic acid.

  It is one of the biomolecules in a living organism which is responsible for the genetic information transfer in our body. The smallest unit of DNA is called as nucleotide which is mainly composed of three components,

Deoxyribose sugar molecule

Nitrogenous base

Phosphate group

These three components bonded with each other to form one nucleotide. Nucleotides are bonded with each other to form DNA molecule
