The anticodons on tRNA are the ones that pair with codons on mRNA during translation.
<h3>Translation</h3>
It is also known as protein synthesis.
During this process, the genetic codes on mRNA, otherwise known as codons, pair with their complementary anticodons on tRNA to release the respective amino acid.
The amino acids are linked together by peptide bonds to give the primary structure of proteins.
