GRE范文 研究表明2021基因其实更“强势”

1、gre范文 研究表明XX基因其实更“强势” 据英国每日电讯报9月28日报道，几世纪以来，女性都被打上弱势性别的标签，但一项新研究表明，事实可能正好相反。 Aording to a study, the fairer _ is geically programmed to better resist infections and can _r, and also have a back-up system for fighting disease。 根据该研究，女性基因更能有效抵抗传染病和癌症，同时其基因还具备一套抵御疾病的支持体系。 The discovery sheds light on w

2、hy members of the so-called stronger _ suumb to _n-flu。 这一发现解释了所谓的强势性别男人总易患流感的原因。 The reason why women are more robust appears to be microRNAs - short strands of RNA encoded on the chromosome, scientists believe. RNA is a geic cousin of DNA and can have important biological effects。 科学家认为，女性更健康的原因可能

3、在于微RNA(核糖核酸)，它是染色体上RNA编码的短片段。而RNA是DNA(脱氧核糖核酸)的基因表亲，具有重要的生物学效应。 The microRNAs have the effect of silencing immunity genes on X-chromosome, aording to the new research. This leaves men at a disadvantage sin _ they only have one X chromosome. Women have two, so that even when immunity genes are silen _

4、d on one the other can pensate. So _ns immune systems are no _tch for those of wives and girlfriends 根据这项新研究，微RNA具有“屏蔽”X染色上的免疫基因的效果。这使只有一条X染色体的男性处于不利地位，而女性拥有两条，所以即使一条上的免疫基因不能发挥作用，另一条上的也能起到弥补作用。所以，男性的免疫系统无法与他们妻子和女朋友的匹敌。 Study leader Dr Claude Libert, from Ghent University in Belgium, said: Statistics

5、 show that in hu _ns, as with other _m _ls, fe _les live longer than _les and are more able to fight off shock episodes from sepsis, infection or trau _. We believe this is due to the X chromosome. 比利时根特大学的研究 _者克劳德力博特 _说：“数据表明，在人类和其他哺乳动物中，女性寿命更长，更能抵御因败血症发作引起的休克、感染病和创伤。我们认为这可以归因于X染色体。” From a biological point of view, the differen _ has probably evolved because women are more likely to ensure the survival of the species. They need to be able to resist infection when pregnant and when nuturing a child。 从生物学角度来说，这种差异的演化可能是出于女性更有可能确保种族生存。她们需要在怀孕和养育子女的时具备抵御传染的
