The "Mg(2+)-Sarkosyl crystals" (M band) technique distinguishes between membrane-bound and free intracellular DNA. This procedure was employed to investigate the nature of the reactions necessary to convert input T4 DNA to a rapidly sedimenting form. Energy poisoning inhibits this attachment reaction. Neither protein nor DNA synthesis appears to be required, but experiments with rifampin and extensively irradiated T4 suggest that RNA synthesis is involved. These results were confirmed by a second procedure for the determination of rapidly sedimenting DNA.
“Mg(2+)- Sarkosyl晶体”(M带)技术可区分膜结合的细胞内DNA和游离的细胞内DNA。该程序用于研究将输入的T4 DNA转化为快速沉降形式所需反应的性质。能量中毒会抑制这种附着反应。似乎既不需要蛋白质合成也不需要DNA合成,但用利福平及经过大量辐照的T4进行的实验表明,RNA合成参与其中。这些结果通过另一种测定快速沉降DNA的程序得到了证实。
