Three types of RNAs : (i) mRNA, (ii) tRNA, (iii) rRNA.
Role
mRNA - provides the template for protein synthesis, by bringing the genetic information from DNA to the site of protein synthesis / ribosome, also provides site to initiate and,terminate the process of protein synthesis.
tRNA - its anti codon loop read the genetic code on mRNA, brings the corresponding amino acid and bound its amino acid binding end on to the mRNA.
rRNA - forms a structural component of ribosome, (23SRNA) acts as a catalyst / ribozyme for the formation of peptide bond.
