Uracil

Detailed explanation-1: -Nitrogen base not found in DNA is uracil. It is found only in RNA.
Detailed explanation-2: -There are two types of nitrogenous group-Purines (adenine and guanine) and pyrimidines (cytosine and thymine). Uracil is present in RNA not in DNA.
Detailed explanation-3: -Explanation: Uracil is a nitrogenous base that is only found in single-stranded RNA-it is not found in DNA.
Detailed explanation-4: -Uracil is one of four nitrogen bases, most frequently found in normal RNA. Uracyl can be found also in DNA as a result of enzymatic or non-enzymatic deamination of cytosine as well as misincorporation of dUMP instead of dTMP during DNA replication.
Detailed explanation-5: -Uracil (U) is one of the four nucleotide bases in RNA, with the other three being adenine (A), cytosine (C) and guanine (G). In RNA, uracil pairs with adenine. In a DNA molecule, the nucleotide thymine (T) is used in place of uracil.
