NEET BIOLOGY

Detailed explanation-1: -There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).

Detailed explanation-2: -Cytosine (C) is one of the four nucleotide bases in DNA, with the other three being adenine (A), guanine (G) and thymine (T). Within a double-stranded DNA molecule, cytosine bases on one strand pair with guanine bases on the opposite strand. The sequence of the four nucleotide bases encodes DNA’s information.

Detailed explanation-3: -Nucleotide The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).

Detailed explanation-4: -IUPAC name or chemical name of cytosine is 4-aminopyridine-2(1H)-one. The chemical cytosine formula is C4H5N3O.

Detailed explanation-5: -DNA contains four nitrogenous bases namely cytosine (C), guanine (G), adenine (A), and thymine (T).
