The genotoxicity of arsenic, which includes the modification of DNA, DNA break damages and DNA repair prevention, may be the most important mechanism of arsenic carcinogenesis.

砷的致癌症机制主要有遗传物质修饰、DNA断裂损伤及活性氧生成等。

Scientists are mostly stumped as to how the radio frequency waves emitted by cellphones, which lack the punch to break chemical bonds or disrupt DNA, might cause cancer.

科学家们主要搞不懂的是，手机所释放的无线电波，连打断化学键或扰乱dna的冲击力都没有，又怎么可能导致癌症呢？

The nonionizing radiation given off by cellphones is too weak to break chemical bonds or damage DNA.

手机发出的非电离辐射很弱，不足以断开化学键或破坏DNA。

Most cancers are the result of unusual changes in your DNA. Chromosomes break and leak into each other, for example, changing a gene's basic essence and sometimes triggering abnormal growth.

FORBES: The Reductive Outsider

From the development of the jet engine and liquid crystal displays, from cracking the inner workings of DNA to pioneering work on Lithium-ion batteries, the country has all too often managed to break new scientific ground but then fail to capitalise on the vast potential that others then enjoy.

Doctors can break up the clot by using Activase, a drug used by Genentech (nyse: DNA - news - people ), but that drug must be used quickly after the stroke happens.
