异染色体

The origin of such large amounts of constitutive heterochromatin and their role in karyotype evolution and speciation remain a mystery.

如此大量的结构异染色质的来源及其在染色体组型进化和物种形成中的任务仍是一个谜。

It contains the largest autosomal block of heterochromatin, which is heteromorphic in 6–8% of humans, whereas pericentric inversions occur in more than 1% of the population.

它具有最大的常染色体异染色质区域，其在6-8％的人群中为异型的，然而中心周围倒位在人群中出现率大于1％。

These variants change the conformation and stability of nucleosome to facilitate transcriptional activation or deactivation, DNA repairing, heterochromatin formation, and others.

这些变体通过改变核小体的空间构象和稳定性，决定基因转录的激活或沉默，DNA的修复，染色体的异染色化等。
