Nitrogenous bases present in the DNA can be grouped into two categories:
|
|
adenine and guanine
|
|
|
cytosine and uracil
|
|
|
purines and pyrimidines
|
|
|
cytosine and thymine
|
Explanation:
Detailed explanation-1: -Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)). These nitrogenous bases are attached to C1’ of deoxyribose through a glycosidic bond. Deoxyribose attached to a nitrogenous base is called a nucleoside.
Detailed explanation-2: -Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .
Detailed explanation-3: -Purines (adenine and guanine) are two-carbon nitrogen ring bases while pyrimidines (cytosine and thymine) are one-carbon nitrogen ring bases.
