查询词典 chromatin

In the past there has been a lot of emphasis on chromatin modifications and physical access to genes, but Scp1 regulates the activity of the enzyme that transcribes genes directly, he adds.

激酶可以为RNA聚合酶 II加上一个小的磷酸盐基团，使RNA聚合酶 II继续转录基因，而Scp1则会移除小的磷酸盐基团，使RNA聚合酶 II停工。

Endo G is a mitochondrial DNA enzyme which translocates to nucleus after releasing from mitochondrion and cuts chromatin DNA into nucleosome fragments in a caspase-independent manner.

Endo G是一种线粒体DNA酶，当其从线粒体释放出来之后，可以转位到细胞核，并且以caspase非依赖性方式将染色质DNA剪切为核小体碎片。

Chromatin unwraps in places where it shouldn't, as sirtuin guardians work overtime putting out fires around the genome, and the unwrapped genes never return to their silent state.
