Describe the structure of a tRNA molecule. Your answer should include a list of five important sites on the tRNA and two reasons why tRNA's modified bases are important
What will be an ideal response?
The five sites are amino acid binding site, ??C stem, variable loop, anticodon stem, D stem, and acceptor stem. The modified bases are important in conferring structural stability and play a role in hydroben bonding between tRNA and mRNA, which helps explain the wobble effect.
