Mr. Sabanayagam studies the epigenome as it relates to microgravity.

Sabanayagam研究微重力下表基。

And that epigenome is constantly changing.

表观基是不断变化。

After about a week the scientists take out the worms. They look for changes in the worms' epigenome.

周后科学家将蠕虫取出，然后观察蠕虫表观基改变。

The epigenome is kinda like Play-Doh on the genome.

表观基有点像基上橡皮泥。

The epigenome also mediates a lifelong dialogue between genes and the environment.

表观基同导终生对话在基和环境中。

As twins get older, their epigenomes diverge, affecting the way they age and their susceptibility to disease.

当双胞胎慢慢长大，它们表观基不，影响他们寿命和他们受疾病损害程度。

The epigenome can be changed by the environment. And those changes pass from one generation of worms to the next.

表观基可以被环境改变，这些改变从代蠕虫传递到下代。

But in addition to the primary sequence of DNA, in addition to the As, Ts, Cs, and Gs, there's our epigenome.

但是除 DNA 初始序列，除 A，T，C 和 G，还有我们表观基。

The set of all of the chemical tags that are attached to the genome of a given cell is called the epigenome.

所有化学标记都依附于染色体，属于个特定细胞被称作是表观基。

A balanced lifestyle that includes a healthy diet, exercise, and avoiding exposure to contaminants may in the long run create a healthy epigenome.

个平衡生活方式包括健康饮食，锻炼，和避免暴露于污染从长远来看，能够创造个健康表观基。

Your mother's or your father's experiences as a child, or choices as adults, could actually shape your own epigenome.

你母亲或者父亲作为孩子经历，或者成为成年人后选择，事实上可能形成你自己表观基。

Each of the approximately 200 cell types in your body has essentially the same genome but its own distinct epigenome.

大约有200细胞类型在你身体里，每个细胞类型都有相同染色体但是拥有他们自己不同表观基。

So when we're young, our epigenome is pristine, it's set with genes on and genes that  are off that maintain a cell's identity.

所以当我们年轻时候，我们表观基是原始，它由维持细胞特性基和关闭基成。
