These reactions influence how our genetic code is expressed: how each gene is strengthened or weakened, even turned on or off, to build our bones, brains and all the other parts of our bodies.

这些反应影响着我们的遗传密码的表现方式：每个基因是如何被加强或削弱，甚至其作用机制是如何被打开或关闭，从而构成我们的骨骼、大脑以及身体的其他部位的。

But because the DNA code itself remained unchanged, Morris's team suggest that the changes in gene expression are epigenetic.

但由于DNA密码本身并无变化，莫里斯的团队认为这些基因表达的调整是表观的。

It took them until now to figure out exactly where in the body's genetic code the gene is.

FORBES: Myriad's Gene Discovery Won't Pay Off--Yet

This month a new scientific paper discussed the finding that small nematode worms of a certain species often carry a particular mitochondrial mutation the absence of 786 letters of code from a crucial gene.
