cytosine (C)

|
uracil (U)

thymine (T)

Detailed explanation-1: -The thymine base of DNA is replaced with uracil in RNA.
Detailed explanation-2: -Nucleotide The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine.
Detailed explanation-3: -Uracil is present in RNA but not in DNA.
Detailed explanation-4: -RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine. Uracil is a pyrimidine that is structurally similar to the thymine, another pyrimidine that is found in DNA.
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.
