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

Sabanayagam研究了微重力下的表基。

And that epigenome is constantly changing.

表观基是断化的。

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

一周后科学家将蠕虫取出，然后观察蠕虫表观基的。

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

表观基有点像基上的橡皮泥。

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

表观基同样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，它们的表观基一样了，影响了他们的寿命和他们受疾病的损害程度。

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，这些从一代蠕虫传递到下一代。

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

但是除了 DNA 的初始序列，除了 A，T，C 和 G，还有我们的表观基。

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

所有的化学标记都依附于染色体，属于一个特定的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.

一个平衡的生活方式包括健康的饮食，锻炼，和避免暴露于污染从长远来看，能够创造一个健康的表观基。

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

你的母亲或者父亲作为孩子的经历，或者成为成年人后的选择，事实上可能形成了你自己的表观基。

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

大约有200细胞类型在你的身体里，每一个细胞类型都有相同的染色体但是拥有他们自己同的表观基。

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.

所以当我们年轻的时候，我们的表观基是原始的，它由维持细胞特性的基和关闭基成。
