What is the role of trna?

a. trna brings over the correct amino acid by using the anticodon to match to the mrna during translation.
b. trna acts as a substitute for mrna when there is a mutation.
c. trna is used in the process of dna replication to bring the correct dna bases to the new strand.

The correct answer is a tRNA brings over the correct amino acid by using the anticodon to match to mRNA during translation

Explanation:

tRNA or Transfer RNA play an important role during the translation process.tRNA contain anticodon that interracts with the codon of mRNA molecule with the help of Ribosome to bring the amino acid to  its own acceptor arm. The amino that is brought to acceptor arm of tRNA is specific for the codon present in mRNA.                

tRNA then moves to the P site and a new tRNA bind to the A site  of ribosome and brings a new  amino acid that form peptide bond with previously generated amino acid. Then process continue untill the tRNA  recognizes a termination or nonsense codon
