Uracil in RNA replaces thymine in DNA, according to ScienceDaily. Both uracil and thymine bond with adenine, the complementary base found in both the RNA and DNA structures. More »

The base pairs in DNA are adenine to thymine and guanine to cytosine. In RNA, they are adenine to uracil and guanine to cytosine. More »

Uracil replaces thymine in RNA because RNA is a more primitive nucleic acid than DNA, and uracil predates thymine. DNA utilizes thymine because it is easier for the cell to detect damage and transcription errors with thy... More »
