WebWhat enables the copied chromosomes to separate during binary fission? a)The septum splits the replicated chromosomes. b)The mitotic spindle drives the separation. c)The nuclear membrane dissolves. d) The chromosomes are attached to different parts of cell membrane, which elongates and thus separates the chromosomes. d 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. phone shop in ware
