u lit meaning in Chinese

无裂口的

Scientists know that u light can cause genetic alterations that preent dna from replicating properly , and these mutations can lead to diseases such as cancer
科学家认为紫外光能导致基因改变阻止dna正常复制并且形成突变导致疾病例如癌症。
That means that whether or not two thymine bases are damaged depends on the position of the dna during the extremely brief time required for it to absorb u light
这就意味者无论两个胸腺嘧啶是否受到损伤都要依赖于在吸收紫外线极端短的时间内dna的位置。
They took specially designed strands of dna - - ones made solely of thymine bases , in order to boost the chance of obsering a reaction between adjacent thymines - - and exposed them to u light
他们设计采用了特异的dna链?为了增加观察临近胸腺嘧啶反应，一条链仅由胸腺嘧啶组成，并且暴露于紫外光下。
This is the first time scientists hae been able to probe the " dark " energy state - - so called because it cannot be detected by fluorescence techniques used to study other high - energy states created in dna by u light
这是科学家首次能够检测到“黑暗状态” ，命名缘于荧光技术下（通常用于检测紫外光在dna产生其他高能状态）无法检测其存在。
