英语翻译
Some genes change rapidly in evolution while others have changed extremely slowly.The rate of change in a gene over time is called the molecular clock.The rate of change in a gene's sequence is probably a function of the tolerance of the gene to changes without disrupting its function.Genes that change very slowly over extremely long periods of time probably do not tolerate change very well and play key roles in the life of cells and organisms.
请帮我翻译一下,我不理解为什么变化很慢的基因是不能很好容忍变化的?是不是我句子意思理解错了还是什么?

有些基因进化快而有些则很慢,这种基因的进化速率就成为分子钟.这种差异很可能是由于不同基因在功能上对突变的耐受程度不同,那些进化缓慢的基因或许就是因为太重要,一旦发生扰乱功能的突变就是致死性的.

段落大意就是说有些基因在细胞中很重要,它们一丁点突变可能就会对细胞的生存构成巨大障碍,所以能存活的突变个体很少,进化就慢了,这些基因就是文章所谓的容忍能力差的.反之有些基因并不是很重要,细胞可以忍受它们的突变,于是……相信你能理解.

有些基因在进化中变化很快,与此同时,有些基因却变化得十分缓慢。
一个基因随时间变化的比率被称为分子钟。
一个基因序列中变化的比例可能是一种功能性的,这种变化不会扰乱该基因的正常功能,因而是可以忍受的变化。
那些长时间缓慢变化的基因可能是完全不能忍受的变化,或者在细胞或生命体中扮演重要的角色。
以人为例,有些基因变化的很快,不同区域的人之间基因频率有很大的差异,而有些基因全世界任何地方基因频率都相同。通过对基因分析发现,凡控制人体次要功能的基因,例如控制毛发颜色的基因,变化很快,凡控制人体主要功能的基因则变化很慢。
我个人认为,重要基因的变化频率可能和其他基因的频率是相同的,但重要基因变化之后,这个个体就无法存活,这个变化的基因随之被淘汰而不能保留。而次要基因不影响存活,或者影响较小,从而使他(她)们能结婚生子,使变化了的基因能够保留下来。

收起

是不是可以这样理
这些起关键作用的基因序列只要发生一点变化,其表达就会受到很大的影响,个体就会非常不适应环境,所以突变的个体在竞争中被完全淘汰,只有没有突变的保留的下来。

他的意思是有些基因在细胞的生命历程中扮演了很重要的角色,不能轻易变化,一旦变化会对其功能有很大的影响.
