Answer 2

Answer:

Uracil is the nitrogenous base that exists in RNA but is absent in DNA.

Explanation:

Uracil or uracil is a nitrogenous base. Represented by the letter U in the genetic code, it is a simple, pyrimidine ring base capable of making two hydrogen bonds, just like thymine. It replaces thymine in DNA to RNA transcription to complement adenine. It is an exclusive base of RNA, that is, it does not occur in DNA.
