Answer:
In RNA Adenine bonds to Uracil
Explanation:
In the transcription a ribonucleic acid (RNA) copy of a DNA (deoxyribonucleic acid) molecule is made.
During transcription of DNA, RNA uses the uracil base, it bonds with the adenine DNA nucleotide. Thymine is not used as a base in any RNA nucleotide. Thymine and Uracil are identical ring structures but there is a methyl group on thymine and uracil contains a hydrogen atom.
