m-RNA is nucleic acid sequence obtained after information carried in a certain DNA sequence is converted to RNA in a process referred to as transcription. this process is catalyzed by the enzyme DNA transcriptase. The resulting m-RNA is then converted to protein in a process called translation. every three nucleotide bases code for one amino acid and if for instance m-RNA strand has a total of 300 bases, a poly-peptide of 100 amino acid will be synthesized.
