HI! RNA acts as the information bridge between DNA and protein. mRNA is the message that carries genetic information from the DNA in the nucleus to the cytoplasm. tRNA is the adaptor that reads the mRNA and brings the amino acids to the ribosomes for protein synthesis.RNA polymerase is an enzyme that makes RNA using a DNA template.
