What base in mRNA can only join with the adenine base of RNA? uracil base of tRNA?

Sagot :

In the transcription process, specific base pairing is important to ensure the right code for amino acids in the protein.  When DNA replicates into mRNA using base pairing--- Guanine-Cytosine and Adenine-Thymine.  Guanine only matches with cytosine and adenine matches to Uracil or Thymine in DNA
