Detailed explanation-1: -Its job is to match an mRNA codon with the amino acid it codes for. You can think of it as a kind of molecular “bridge” between the two. Each tRNA contains a set of three nucleotides called an anticodon. The anticodon of a given tRNA can bind to one or a few specific mRNA codons.

Detailed explanation-2: -Anticodons are found on molecules of tRNA. Their function is to base pair with the codon on a strand of mRNA during translation. This action ensures that the correct amino acid will be added to the growing polypeptide chain. A tRNA molecule will enter the ribosome bound to an amino acid.

Detailed explanation-3: -Only the tRNA carrying the next amino acid in the polypeptide chain has the anticodon that binds to the appropriate location on the mRNA. This system ensures that amino acids are added to the chain in the correct order.

Detailed explanation-4: -The anticodon enables the tRNA to recognize the codon through complementary base pairing. The events in protein synthesis are catalyzed on the ribosome, which consists of two subunits; each subunit consists of several proteins associated with a long RNA (rRNA).

Detailed explanation-5: -Anticodon Each time an amino acid is added to a growing polypeptide during protein synthesis, a tRNA anticodon pairs with its complementary codon on the mRNA molecule, ensuring that the appropriate amino acid is inserted into the polypeptide.
