The genetic switch involves acetylation, the introduction of an acetyl group into a molecule at the DNA level of chromatin resulting in genetictranscription.
基因“开关”涉及乙酰化作用,也就是将乙酰基群在染色质的DNA水平上引入到分子中,由此完成基因转录。

Functional aspects of nuclear: : It is the largest organelle in the cell and the place for genetic storage, replication and transcription.
细胞核的功能:细胞核是真核细胞中最大的细胞器,也是遗传物质储存、复制和转录的场所。

Transcription is the first major step in gene expression, and constitutes an important point of genetic information flow.
