1. main parts and their role:
Anticodon loop – It has been complementary to the code.
Amino acid acceptor end. It binds to amino acids.
2. Activation of amino acids in presence of ATP and linking to tRNA is called aminoacylation or charging of tRNA.
3. At the end of translation, a release factor binds to the stop codon, to terminate translation and release polypeptide from ribosome.
