Question

multiple choice question
the anticodon found on a molecule of trna:

is complementary to the codon on a molecule of mrna.

is complementary to the amino acid sequence

is complementary to the codon on a molecule of dna.

Explanation:

To solve this, we recall the role of tRNA in translation. The anticodon of tRNA pairs with the codon of mRNA via complementary base - pairing (A - U, G - C) to bring the correct amino acid. The amino acid sequence is determined by the codons, and tRNA's anticodon doesn't pair with it. Also, DNA has codons (in the sense strand) but tRNA interacts with mRNA during translation, not directly with DNA codons. So the anticodon on tRNA is complementary to the codon on mRNA.

Answer:

A. is complementary to the codon on a molecule of mRNA.
