| Abstrakt: | IT has been reported that cytological preparations of chromosomes can serve as templates in RNA polymerase reactions1–2. The newly synthesised RNA on chromosomes was readily digested with RNase in contrast to RNA which was synthesised in a similar manner but using as a template denatured DNA immobilised on nitrocellulose filters1. When cytological preparations of chromosomes were pretreated with poly-L-lysine (PL), no synthesis of RNA could be demonstrated2. The implication was that bound PL blocked those sites on DNA template which were responsible for transcription. |
