组蛋白赖氨酸甲基化是组蛋白尾段发生的一种重要共价修饰，在基因的表观遗传转录调控中起着关键的作用。

The methylation of histone lysine is an important covalent modification at its tails and plays a key role in epigenetic regulation.

遗传暗物质也隐约大时，科学家调查哪些基因被转录，或解码成rna。

Genetic dark matter also loomed large when scientists surveyed exactly which DNA was being transcribed, or decoded, into RNA.

逆转录病毒的遗传物质是RNA，一种类似但又区别于DNA的分子。

The hereditary material of a retrovirus is a molecule called RNA, which is similar to, but distinct from, DNA.

So, its genetic material wouldn't be released and even if it was released, the genetic material is also cross-linked, and so it can't be transcribed and translated or replicated.

不能释放遗传物质,而且即使能释放遗传物质,该物质也是交联的,因此转录和翻译,即复制过程不能进行
