likoan [24]

Answer:

C) the three-base sequence of mRNA

Explanation:

Three-base sequence of mRNA is called codon. One codon specifies a single amino acid. There are 64 codons in eukaryotic cells and three of them are stop codons (non-coding).

tRNA have three-base sequence called anticodon which is complementary to specific codon. During the process of translation codon and anticodon are paired which leads to addition of amino acid to growing polypeptide chain. Newly added amino acid is carried by tRNA.
