molecular clock

基本解释

• [仪] 分子钟

英汉例句

双语例句

• However, the origin time inferred by molecular clock is always earlier than that by the fossil record. This approach is still controversial.
  然而，利用分子钟方法所得出的不同门类起源时间总是早于化石记录，因此分子钟与化石记录的矛盾仍十分突出。
• But what has made this molecular clock so useful for forensic anthropologists over the past quarter-century is the fact that it stops dead when someone dies.
  但为何这个分子时钟在过去四分之一世纪中对于法医学家如此有用呢？ 究其实是因为某人死去时它突然停止，凝滞了死亡瞬间。
• As a molecular clock and genetic marker, superoxide dismutase has been widely used in evolutionary studies, population genetics, and identification of different strains in the same species.
  因此，超氧化物歧化酶作为分子钟或分子标记已被广泛应用于生物进化研究、群体遗传结构分析以及品系鉴定。

• 分子钟

  Molecular clock and megafossil bearing reproductive features indicate remarkable discrepancy on minimum age of Ephedra L. Three different explanations at least are present on the conflicts:Paleogene bottleneck,extinction of ancient lineages,and frequent gene exchanges in the genus.
  利用分子钟对麻黄属起源时间的估测和基于带有生殖特征的大化石标定的最小起源时间有很大的差距,分子钟估测麻黄属起源于古近纪的渐新世,而大化石则标定麻黄属起源不晚于早白垩世巴列姆期。 麻黄属化石和分子钟结果之间的冲突至少有三种不同的解释:即古近纪瓶颈、古老支系缓慢绝灭和频繁的基因交流减缓了分子进化速率。
