Transfer RNA or t RNA help in transfer of amino acids to ribosomes m RNA complex to form the polypeptide chain. It has four key regions a carrier and recognition end, enzyme site and ribosome site. This recognition end has three anticodons with the help of which amino acids are identified. rRNA forms 67% of 70S ribosomes and 50% of 80S ribosomes. mRNA carries the coded information from DNA for the synthesis of proteins.
