Function of tRNA and mRNA

1. mRNA (messenger RNA):

  • Carries genetic code from DNA in the nucleus to the ribosome for protein synthesis.

  • Codons (triplets of nucleotides) on mRNA specify amino acids in a sequence.

  • Example: AUG (start codon) codes for Methionine in translation initiation.

2. tRNA (transfer RNA):

  • Delivers specific amino acids to the ribosome during translation.

  • Has an anticodon loop complementary to the mRNA codon and an amino acid attachment site.

  • Example: tRNA^Met carries Methionine to the AUG codon.
