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: -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.
Detailed explanation-3: -The tRNA carries the amino acid that corresponds to that codon. The next mRNA codon is now exposed in the ribosome’s other docking site. A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain.
Detailed explanation-4: -transfer RNA (tRNA), small molecule in cells that carries amino acids to organelles called ribosomes, where they are linked into proteins.
