Question

click the three letters that make up the next mrna codon.

mrna codon
first letter second letter third letter
u u u
c c c
a a a
g g g

describe what appears.
i need a hint

a trna molecule with an
anticodon that matches the
mrna and the same amino acid
as the first trna molecule.

a trna molecule with an
anticodon that matches the
mrna and a different amino acid
than the first trna molecule.

Explanation:

In translation, tRNA anticodons are complementary to mRNA codons and carry specific amino acids. If the mRNA codon is the same as a previous one (implying the same genetic code), the tRNA with the matching anticodon will carry the same amino acid (due to the genetic code's redundancy or consistency for the same codon). So the first option is correct as the same codon codes for the same amino acid, so the tRNA with the matching anticodon will have the same amino acid as the first tRNA for that codon.

Answer:

A. A tRNA molecule with an anticodon that matches the mRNA and the same amino acid as the first tRNA molecule.
