Histone proteins both protect DNA and regulate genes as they combine with DNA to form chromatin.
组蛋白既保护DNA也在它们与DNA结合形成染色质时调节基因表达。
Chromatin consists of coiled DNA bound to basic proteins called histones and non-histone proteins.
染色质由卷曲的DNA、组蛋白和非组蛋白组成。
DNA and histone proteins are packaged into structures called chromosomes. Image courtesy of the u.

真核生物的基因组dNA连同带正电荷的组蛋白和其它核蛋白组成了染色质。
Histone deacetylase inhibitors increase the acetylation level of histone as well as some non-histone proteins, and specifically modulate some gene expression.
组蛋白去乙酰酶抑制剂可提高组蛋白的乙酰化水平，并对一些非组蛋白成分产生影响，从而调节某些特定基因的表达。
Nucleosomes are grape-like structures formed by strands of DNA wrapped like vines around histone proteins, and serve to organize enormously long DNA molecules.
核小体有着葡萄状结构，由葡萄藤样的DNA链环绕组蛋白所形成，其作用是组织极长的DNA分子。
