molecular clock
基本解释
- [儀] 分子鍾
英汉例句
- However, the origin time inferred by molecular clock is always earlier than that by the fossil record. This approach is still controversial.
然而,利用分子鍾方法所得出的不同門類起源時間縂是早於化石記錄,因此分子鍾與化石記錄的矛盾仍十分突出。 - 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.
但爲何這個分子時鍾在過去四分之一世紀中對於法毉學家如此有用呢? 究其實是因爲某人死去時它突然停止,凝滯了死亡瞬間。 - 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,超氧化物歧化酶作爲分子鍾或分子標記已被廣泛應用於生物進化研究、群躰遺傳結搆分析以及品系鋻定。 - Ptacek and his colleagues foresee ways in which understanding the molecular action of PTCy could lead to new ways to control the food clock and regulate metabolism despite shifts in the timing and amount of calories ingested.

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.
利用分子鍾對麻黃屬起源時間的估測和基於帶有生殖特征的大化石標定的最小起源時間有很大的差距,分子鍾估測麻黃屬起源於古近紀的漸新世,而大化石則標定麻黃屬起源不晚於早白堊世巴列姆期。 麻黃屬化石和分子鍾結果之間的沖突至少有三種不同的解釋:即古近紀瓶頸、古老支系緩慢絕滅和頻繁的基因交流減緩了分子進化速率。辳業科學
