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.
但這些變化并不像成功的基因突變一樣，能夠永久地遺傳下去，實(shí)際上它們往往在一兩代的時(shí)間里就會(huì)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(zhǎng)優(yōu)勢(shì)的細(xì)胞能迅速繁殖，成為優(yōu)勢(shì)種群。但是，這通常是由基因突變引起，并不是我們所期望的正常生長(zhǎng)。
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(gè)子不高的人會(huì)有很少見(jiàn)的基因突變，也就是“高壽基因”，它可以延長(zhǎng)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.
人類食用黃酮類化合物的歷史悠久,然而,高劑量的攝入黃酮類化合物,反而會(huì)作為促氧化劑,形成脂質(zhì)過(guò)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(jī)體免疫應(yīng)答、出現(xiàn)耐藥性、改變致病性和引起疾病流行等有關(guān)。
