6 ημέρες πριν · 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.
Uracil is only found in RNA and not in DNA. It forms two hydrogen bonds with adenine during RNA synthesis. Uracil is a pyrimidine, similar to cytosine and thymine. The presence of uracil instead of thymine helps distinguish RNA from DNA in cells.
