Answer #1

The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA. Adenine (A) and guanine (G) are double-ringed purines, and cytosine (C) and thymine (T) are smaller, single-ringed pyrimidines. The nucleotide is named according to the nitrogenous base it contains.

Phosphate он Deoxyribose sugar

Figure 1: Each DNA nucleotide is made up of a deoxyribose sugar, a phosphate group, and a nitogenous base.

Purines Pyrimidines NH2 NH2 NH2 NH HN NH2 Guanine Base Thymine Base Cytosine Base Adenine Base

Figure 2: Structures of nitogenous base.

The basic properties of DNA bases is observed due to the presence of amine group(-NH2) of the following nitrogenous bases.
