- In particular, they used a molecular clock rate derived from invertebrates, which is slower than the one based on vertebrates. 特别的是，他们使用从无脊椎动物推衍出的分子时钟，速度比脊椎动物的分子时钟要快得多。
- Her age is calculated based on the molecular clock technique of correlating elapsed time with observed genetic drift. 她的年龄计算是基于与随着时间流逝而观测到的基因演变相关的分子钟技术。
- However, the molecular clock is almost always violated in comparisons of distantly related species, such as different orders of mammals. 另一方面，在远缘物种（例如哺乳纲不同目的动物）的比较中，分子钟几乎总是不成立的。
- Although genes relevant to hemostasis and vascular integrity undergo circadian oscillation, the role of the molecular clock in thrombotic events remains to be established. 已知止血和血管完整性的相关基因受昼夜摆动的影响，但分子钟在血栓形成过程中的作用尚有待确定。
- Built on the primary principle of Molecular systematics, DNA sequence data and “Molecular clock” method have been discussed in studies of phylogenetic reconstruction. 本文基于分子系统学的基本原理，探讨了DNA序列数据和“分子钟”方法在重建系统发育研究中的演化时序问题。
- Follow-up studies using the molecular clock produced estimates for this split that varied significantly, ranging from as old as one billion years ago to as young as just before the Cambrian period. 后来使用分子时钟来估算分支时间的研究结果，差异都很大，可能早至10亿年前，晚至寒武纪即将开始时。
- To estimate the timing of the origin of various major animal groups, Gregory Wray of Duke University and his colleagues used a molecular clock rate based on vertebrates (animals that have a backbone). 为了估计各个主要动物类群的起源时间，美国杜克大学的瑞伊（GregoryWray）与同事使用了以脊椎动物为基础的分子时钟。
