The RNAs are of 3 types
- Messenger RNA (m – RNA)
- Transfer RNA (t – RNA)
- Ribosomal RNA (r – RNA)
m – RNA It provides the template for polypeptide synthesis, ie., it decides the sequence of amino acids in the polypeptide through the sequence of bases on it. t – RNA It has the shape of clover leaf in two dimensional structure It transports the amino acids to the site of protein synthesis it recognises the codon on m RNA. r – RNA It plays the structural and catalytic role during translation.
