Purpose: biochemical research. A class of small molecular RNA that specifically transports amino acids in protein biosynthesis and ensures the accurate transmission of genetic information from nucleic acids to proteins. Each amino acid has more than one corresponding tRNA, and each cell has about 40 ~ 70 different tRNAs, which are respectively composed of 72 ~ 93 nucleotides, of which 5 ~ 20% are rare bases. The average relative molecular weight is 25000, and the sedimentation coefficient is 4S. The primary structure of different tRNAs is different, but they have common secondary structure characteristics of clover. Among them, the 3 ′ terminal-c-c-a-oh on the amino acid arm is the site of binding amino acids, and the acyl group of amino acids is attached to the 3 ′ hydroxyl group of the corresponding trna3 ′ terminal adenosine under the catalysis of a specific aminoacyl tRNA synthetase; Three consecutive nucleotides in the anti codon ring form the anti codon, which is complementary to the codon of mRNA on ribosomes, so that amino acids can be accurately positioned to synthesize polypeptide chains. Through the corresponding relationship between code anti code amino acids, the accurate transmission of information from nucleic acid to protein is ensured. TRNA plays an important adaptor role
