A restriction enzyme analysis was performed on satellite DNA components, isolated, as described in the preceding paper, from the bovine genome by a combination of Cs2SO4/BAMD and Cs2SO4/Ag+ density gradient centrifugation. Such an analysis has led to the unambiguous identification of eight satellite DNA components and to new information on their repeat units; this indicates that identical repeat lengths are shared by them, a fact strongly suggesting a common origin.
如前文所述，通过硫酸铯/溴化乙锭密度梯度离心和硫酸铯/银离子密度梯度离心相结合的方法，从牛基因组中分离出卫星DNA组分，并对其进行了限制性内切酶分析。这样的分析明确鉴定出了8种卫星DNA组分，并获得了有关其重复单元的新信息；这表明它们具有相同的重复长度，这一事实强烈暗示了它们有共同的起源。
