These paralogous genes have arisen by repeated duplication of an ancestral gene.
这些平行进化同源基因是通过重复复制祖先基因而产生的。
One-time use of cocaine increases levels of G9a. But repeated use works the other way, suppressing the protein and reducing its overall control of gene activation.
吸食一次可卡因会增加G9a的浓度，然而上瘾之后反而会使其浓度降低，抑制蛋白质的活动，削弱其对基因开关的全面控制。
A partial tandem duplication is a type of gene mutation that occurs when a section of a gene is repeated, like a stutter in the gene's DNA.
部分串联复制是基因突变的一个类型，当一个基因片断重复时发生，就像停顿基因。
