Why is the specific base pairing essential to the process of transcription and translation?

Specific base pairing is essential to transcription to ensure the correct sequence of the mRNA. The transcription process ensures the right code for amino acids in the protein. The correct amino acids are inserted into the growing polypeptide by base pairing: the tRNAs have anticodons that bind to the mRNA at the ribosome.
