role of rna

• • Rna plays an important role in expressing the information contained in the DNA sequence to synthesise polypeptide
• • mRNA– carries a complimentary copy of the DNA sequence for a particular polypeptide from the nucleus to ribosomes in the cytoplasm
• • tRNA- transfers amino acids to the ribosomes, where they are joined form a polypeptide chain based on the sequence of nucleotides in the mRNA
• • rRNA- forms the structural units of ribosomes which is where mRNA is translated into a chain of amino acids
