Detailed explanation-1: -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: -Transfer RNA (tRNA) has a long-established role in protein synthesis. The tRNA molecule serves as an adaptor [1] between the genetic instructions written in nucleic acid sequences and the protein products encoded in genes.
Detailed explanation-3: -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-4: -When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain. Then the tRNAs and ribosome continue to decode the mRNA molecule until the entire sequence is translated into a protein.
Detailed explanation-5: -The role of tRNA is to read the message of nucleic acids, or nucleotides, and to convert it into proteins or amino acids.
