tRNA acts as éx vehicle to pick up amino-acid scattered in the cytoplasm. tRNA has an ntioodonloop of ‘7’ bases. It possesses bases complementary to code, and it also has an amino acid acceptor through hich it binds to amino acids
It is held in clover leaf shape. There is another Specific tRNA, called the initiator tRNA. There are 5 Arm Amino acid attachment Dehydro uracil ,Anticodon ,T-loop ribosome recognition and hump or variable arm.
(b) tRNA 18 called an adaptor molecule because on one and it reads the code on mRNA and on other hand it would bind to specific amino ecid.
