Definition
Transfer RNA (tRNA) is a type of RNA molecule that serves as an adaptor in protein synthesis, facilitating the translation of messenger RNA (mRNA) codons into specific amino acids. Each tRNA molecule carries a specific amino acid and has an anticodon region that pairs with the corresponding codon on the mRNA strand during translation.
Summary
Transfer RNA (tRNA) is a vital component of the protein synthesis process in cells. It serves as the intermediary that translates the genetic code carried by messenger RNA (mRNA) into a sequence of amino acids, which are the building blocks of proteins. Each tRNA molecule is specific to one amino acid and contains an anticodon that pairs with a corresponding codon on the mRNA, ensuring the correct amino acid is added to the growing polypeptide chain. Understanding tRNA is essential for grasping how proteins are made, which is fundamental to all biological processes. Its role extends beyond basic biology, impacting fields like genetic engineering and biotechnology, where tRNA is utilized to develop new therapies and enhance our understanding of genetic functions.
