mRNA are known as messenger RNA. It is the longest RNA compared to tRNA and rRNA. mRNA are made from the transciption of DNA. mRNA is made for protein synthesis which take place in the Rough Endoplasmic Reticulum or in the cytoplasm. tRNA have a "clover leaf" stucture. It is used to bind with amino acids to form aminoacyl-tRNA complex.This reaction is catalysed by aminoacyl-tRNA synthetase enzymes.tRNA is used to transfer amino acids to the ribosomes to synthesis polypeptide chain in the translation process of protein synthesis.
