Question

1. the “words” on the mrna strand are called______________________. the complementary “words” on trna molecules are called__________________.

Explanation:

In molecular biology, mRNA (messenger RNA) has triplet nucleotide sequences called codons. These codons code for specific amino acids. tRNA (transfer RNA) has complementary triplet nucleotide sequences called anticodons. The anticodons on tRNA pair with the codons on mRNA during translation to ensure the correct amino acid is added to the growing polypeptide chain.

Answer:

codons; anticodons
