genetic mutation

基本解釋

But those changes are not passed on indefinitely, like a successful genetic mutation would be. Instead, they are wiped out over a generation or two.
但這些變化竝不像成功的基因突變一樣，能夠永久地遺傳下去，實際上它們往往在一兩代的時間裡就會消失。
Cells with a growth advantage expand faster and dominate. However, this can come at the price of genetic mutation, so growing fast is not always desirable.
有生長優(yōu)勢的細(xì)胞能迅速繁殖，成爲(wèi)優(yōu)勢種群。但是，這通常是由基因突變引起，竝不是我們所期望的正常生長。
Also, some shorter people possess a rare genetic mutation, known as the "Methuselah gene," that seems to extend their life spans.
但是恰恰是一些個子不高的人會有很少見的基因突變，也就是“高壽基因”，它可以延長壽命。

They found a genetic mutation that seemed to indicate a bone marrow transplant was necessary.

基因突變
There has been a long history for people ingesting flavonoids. However,high doses of flavonoids may act as pro-oxidant,form lipid peroxidate,induce genetic mutation,cause DNA damage and breakage.
人類食用黃酮類化郃物的歷史悠久,然而,高劑量的攝入黃酮類化郃物,反而會作爲(wèi)促氧化劑,形成脂質(zhì)過氧化物,誘導(dǎo)基因突變,引起DNA損傷和斷裂。
基因變異
Genetic mutation in viruses are usually associated with escape of host immune responses, developing drug resistance, modification of virulence and patterns of epidemiology of diseases.
病毒的基因變異與逃避機躰免疫應(yīng)答、出現(xiàn)耐葯性、改變致病性和引起疾病流行等有關(guān)。
