Detailed explanation-1: -Transfer RNA (tRNA) molecules serve as molecular adaptors that bind to mRNA on one end and carry amino acids into position on the other. Most types of cells possess approximately 30 to 40 different tRNAs, with more than one tRNA corresponding to each amino acid.
Detailed explanation-2: -The secondary structure of tRNA looks like a clover leaf and tertiary structure is like an inverted ‘L’ shape. The folded structure is formed due to hydrogen bonding between complementary bases. It is formed by the base pairing of 7-9 nucleotides of 5’ terminal and 3’ terminal.
Detailed explanation-3: -tRNA has a structure resembling clover leaf. The structure of tRNA can be decomposed into its primary structure, its secondary structure usually visualized as the cloverleaf structure, and its tertiary structure.
Detailed explanation-4: -tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges, ” matching a codon in an mRNA with the amino acid it codes for.
