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.

Answer:

DNA has three types of components:

  1. Deoxyribose sugar.
  2. Nitrogenous bases.
  3. Phosphate group.

Step-by-step explanation:

DNA is composed up of molecule nucleotide and each nucleotide comprises of a Deoxyribose sugar, a phosphate group, and nitrogenous bases.

Deoxyribose sugar.is a five carbon or a pentose sugar.

phosphate group:help in the formation of DNA backbone.

nitrogenous bases: is used in the formation of nucleotides. The nitrogen bases are purines( adenine, guanine), pyrimidines (cytosine, and thymine).
