Question

What are the features of sites of tRNA which are in distinct sites on ribosomes?

Answer 1

tRNA:

1. On ribosomes, each type of tRNA has its own location.
2. There are two different sites with different features - The A location is occupied by aminoacyl-tRNA.
3. The location reveals a codon indicating the next amino acid to be added to the chain before it enters to bind.
4. Peptidyl tRNA - tRNA, which carries the nascent polypeptide chain - controls the P site, which has a codon that specifies the most recent amino acid added to the chain.
