WebThe charged tRNA can then be used in the process of translation, where it brings the correct amino acid to the ribosome for incorporation into the growing protein chain. The accuracy of the charging reaction is crucial for proper translation and protein synthesis. Web16.12.1 Introduction. Transfer-RNA molecules (tRNA) are crucial to protein translation as they decode the genetic code held on messenger RNA for a particular protein. Each tRNA …

WebDuring translation, these tRNAs carry amino acids to the ribosome and join with their complementary codons. Then, the assembled amino acids are joined together as the … WebtRNAs bind to mRNAs inside of a protein-and-RNA structure called the ribosome. As tRNAs enter slots in the ribosome and bind to codons, their amino acids are linked to the growing polypeptide chain in a chemical reaction. The end result is a polypeptide whose amino acid sequence mirrors the sequence of codons in the mRNA.
