Which base is found in RNA but not DNA?

Explanation:
RNA uses uracil instead of thymine, which is why uracil is found in RNA but not DNA. In RNA, the bases are adenine, cytosine, guanine, and uracil, with adenine pairing to uracil. DNA, on the other hand, uses thymine instead of uracil, so thymine is not present in RNA. The other bases—adenine, cytosine, and guanine—are common to both nucleic acids.
