t-RNA has an anticodon loop that has bases complementary to the code, and it has also an amino acid acceptor end to which amino acid binds.
Amino acid are activated in the presence of ATP, and linked to their cognate t-RNA, called as charging/ amino-acylation of t-RNA.
Initiator t-RNA recognises start codon (AUG)/t-RNA act as the adapter molecule that reads the genetic code. Two such charged t-RNA are brought close enough to favour peptide bond formation. t-RNA (transfer RNA) reads the genetic code on one hand & transfers amino acids on the other hand, so it is called as adapter molecular by Francis Crick.
