WebThe first step in decoding genetic messages is transcription, during which a nucleotide sequence is copied from DNA to RNA. The next step is to join amino acids together to form a protein. The order in which amino acids are joined together determine the shape, properties, and function of a protein. WebAn aminoacyl-tRNA synthetase (aaRS or ARS), also called tRNA-ligase, is an enzyme that attaches the appropriate amino acid onto its corresponding tRNA.It does so by catalyzing the transesterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA.In humans, the 20 different types …

WebApr 8, 2008 · As adaptor molecules linking the codons in a mRNA to the amino acids that they specify, aminoacyl-tRNAs (AA-tRNAs) play a central role in protein biosynthesis. In addition to this critical role, AA-tRNAs are also involved in several other less well known but still important biochemical reactions ( Fig. 1 ). During translation, ribosomes synthesize polypeptide chains from mRNA template molecules. In eukaryotes, translation occurs in the cytoplasm of the cell, where the ribosomes are located either free floating or attached to the endoplasmic reticulum. In prokaryotes, which lack a nucleus, the processes of both transcription and translation occur in the cytoplasm.
