Answer:
B. Specific codons pair with specific anti codons.
Step-by-step explanation:
The nucleotide sequence of mRNA serves as a template for protein synthesis. During the process of protein synthesis, the mRNA nucleotide sequence is read in the form of triplet codons. The tRNA with the complementary anticodon sequence joins the mRNA.
There is base pairing between codon of mRNA and its complementary anticodon of tRNA followed by the formation of a peptide bond between existing amino acid on the ribosome and incoming amino acid carried by tRNA.
