Which base is Uracil?

Explanation:
Uracil is a base used in RNA. It is one of the four nucleobases in RNA (the others being adenine, cytosine, and guanine) and it pairs with adenine during RNA base pairing. DNA, on the other hand, uses thymine instead of uracil. The presence of uracil in RNA and thymine in DNA helps distinguish the two types of nucleic acids, also reflecting the sugar differences (ribose in RNA vs deoxyribose in DNA).
