The function of /RNAs or transfer RNA is to pick up particular amino acid (at CCA or 3' end) in the process called charging. The charged tRNAs take the same to mRNA over particular codons corresponding to their anticodons during protein synthesis. Anticodon loop has 7 bases out of which three bases form anticodon for recognizing and attaching to the codon of mRNA. There are different t RNAs for different amino acids. Each t RNA has an area for coming in contact with ribosome (TΨC) and the enzyme amino acyl tRNA synthetase (DHU) that helps in combining amino acid to its particular tRNA. There is, however, no tRNA for stop signals. Therefore, when stop signals are encountered, they cannot be recognised by tRNA and protein synthesis stops.
