"WebTherefore, if we have a gene that is 1200 nucleotides long (which is about average), it will take ~2 minutes to transcribe into 1200 nucleotides of mRNA and ~20 seconds to translate that into a 400 amino acid protein. Bacteria actually start translating the mRNA before they've finished transcribing it. " - Chromosomes replicate
