Transcription is the mode by which DNA passes its genetic information to mRNA. It is the first step in protein synthesis, which takes place in nucleus of eukaryotic cells. Translation is the synthesis of a chain of polypeptide by mRNA. It is the process when protein synthesis takes paice at the site of ribosomes.
