Fact 5: Much of this variation is heritable.
This variation is very slow.Combinations with other parts of speech
We can handle this mutation by doing function composition, or function chaining.
That variation tends to be associated with liberals.
The team found 212 regions with such variation.
And some cells may not tolerate such changes.
Nobody knows what could cause such fluctuations.这种变异有助于生物在不断变化的环境中快速进化,帮助它们统治地球达1.8亿年之久。
This variation helped the creatures evolve quickly in response to a changing environment- helping them to dominate Earth for 180 million years.这种变异与称为PM20D1的神经保护基因的活性丧失有关;
This variation is associated with the loss of activity of a neuroprotective gene called PM20D1;近30亿人拥有这种变异,这就意味着,他们都有一个共同的祖先。
Nearly 3 billion men shared this mutation, and it means they're all descended from one man.研究人员说,通过减少这种变异并进一步降低发病率,许多癌症可以在早期被诊断甚至被预防。
By reducing this variation, and lowering rates further, many cancers could be diagnosed at an earlier stage or even prevented, say the researchers.只是因为一个人的DNA含有这种变异并不意味着他们会患偏头痛,”Weyer通过电子邮件说.
Just because a person's DNA contains this variant does not mean that they will suffer from migraines," Weyer said by email.使用统计建模,这种变异已经独立于1819年左右,这与历史记录一致。
Using statistical modelling, this mutation has been independently dated to around 1819, which is consistent with the historical record.这种变异受到干旱的严重程度以及人对生态系统资源的压力所推动。
This variability is driven by the degree of aridity combined with the pressure people put on the ecosystem' s resources.基因测试可以很轻松地确定哪些儿童带有这种变异,这样可以让他们的家长避免那些不必要的指责。
Genetic tests could easily clarify whether those children had this mutation, so that their parents are not needlessly blamed.研究人员说,通过减少这种变异并进一步降低发病率,许多癌症可以在早期被诊断甚至被预防。
By reducing this variation, and lowering rates further, many cancers could be prevented or diagnosed at an earlier stage, say the researchers.不出所料,这种变异使得蛋白质与强壮的运动员有相互关系。
Unsurprisingly, this variant that makes the protein has been associated with power athletes.
Both diagnosing this variant of the disease and treating it is costly and demanding.因为支配的雄性会发出最一致的歌,这种变异可能会产生重要的生物学后果。
Since dominant males produce the most consistent songs, this variation could have important biological consequences.”.这种变异自然存在于人类中,并导致对最常见的HIV病毒具有高水平的抵抗力。
This variant naturally occurs in the human population, and results in a high level of resistance to the most common type of HIV virus.然而,到目前为止,很少有研究试图确定这种变异可能对人类产生的生理作用。
Until now, however,few studies have attempted to determine the physiological role this variation might have in humans.这种变异,称为非整倍性,与许多癌症类型中发生的变异相似。
Such variations, named aneuploidies, are similar to those occurring in many cancer types.该研究小组无法确定任何其他拥有两份这种变异的家庭成员也携带有PSEN1E280A突变。
The team was unable to identify anyadditional family members who had two copies of this variation who also carried the PSEN1 E280A mutation.在这项发现之后不久,其他科学家就确定,携带这种变异GR量高于平均水平的人患心脏病的风险更大。
Jan. Soon after the discovery,other scientists determined that people with above average amounts of this altered GR had greater risk of heart disease.
