WebMay 7, 2024 · The ribosome reads the sequence of codons in mRNA, and molecules of tRNA bring amino acids to the ribosome in the correct sequence. To understand the role of tRNA, you need to know more about its structure. Each tRNA molecule has an anticodon for the amino acid it carries. An anticodon is complementary to the codon for an amino acid. WebAminoacyl-tRNA synthetase is responsible for "charging" tRNA with amino acids. During translation, tRNA molecules that are bound to specific amino acids are fed into the ribosome in a specific order that is complementary to the mRNA strand. Once a tRNA is used up, it loses its amino acid. As a result, it must interact with aminoacyl-tRNA ...
