Detailed explanation-1: -Definition. Transfer RNA (abbreviated tRNA) is a small RNA molecule that plays a key role in protein synthesis. Transfer RNA serves as a link (or adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a protein.
Detailed explanation-2: -tRNA carries the amino acids from the amino acid pool to mRNA during protein synthesis.
Detailed explanation-3: -transfer RNA (tRNA) – a type of RNA that is folded into a three-dimensional structure. tRNA carries and transfers an amino acid to the polypeptide chain being assembled during translation. translation – the process in which a cell converts genetic information carried in an mRNA molecule into a protein.
Detailed explanation-4: -tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges, ” matching a codon in an mRNA with the amino acid it codes for.
