The chromosomes uncoil back into chromatin.

染色体解卷回染色质。

It is not established, however, that the endonuclease-induced DNA fragmentation itself causes the chromatin condensation.

细胞体积和形变部分归因于凋亡细胞内谷氨酰胺转移酶活性诱导。

The chromatin aggregates peripherally under the nuclear membrane, into well-delimited dense masses of various shapes and sizes.

细胞核本身可能崩解，产生两个或多个核碎片。

They found that it binds to chromatin, the compact structure that allows long molecules of DNA to ball up and fit into a tiny cell.

研究员认为，Dsup作为一种染色质绝缘体，可以保护DNA免受羟基自由基攻击。

It usually involves several genetic mutations in endometrial cells, including of PTEN, a tumor suppressor gene; PIK3CA, an oncogene; and ARID1A, a gene regulating chromatin structure.

它通常涉及子宫内膜细胞几种基因突变，癌基因PTEN、原癌基因PIK3CA，及调控染色质结构基因ARID1A。

These machines are called chromatin remodelers, and the way they work is that they basically scoot the DNA around these histones and they allow new pieces of DNA to become exposed.

这些“机器”被称为染色质重塑器，它们载着 DNA在组蛋白上移动，让新 DNA 片段暴露出来。

Many different environmental stressors have been shown to alter the chromatin and epigenetic marks of plants, providing evidence within their chromosomes that they do indeed have memories of stress.

许多不同环境压力因素已被证明可以变植物染色质和表观遗传标记，从而在它们染色体中提供证据表明它们确实具有压力记忆。
