Question

explain the roles of mrna and trna in protein synthesis.

Explanation:

mRNA (messenger RNA) carries genetic information from DNA in the nucleus to the ribosomes in the cytoplasm. It serves as a template for protein synthesis. tRNA (transfer RNA) has an anticodon that pairs with a codon on mRNA and carries the corresponding amino acid to the ribosome for addition to the growing polypeptide chain.

Answer:

mRNA carries genetic info as a template. tRNA brings amino acids via anticodon - codon pairing.
