When it binds, those cells activate the JAK2 gene which makes them divide and mature into megakaryocytes and platelets.

当结合后，细胞激活JAK2基因，促使这些细胞分化、成熟，变为巨核细胞和血小板。

The team devised a cocktail of drugs designed to activate the genes that they knew were expressed in functioning ameloblasts.

该团队设计了一种混合药物，旨在激活他们已知的在功能成釉细胞中表达的基因。

Chemicals like salicylic acid, for instance, might also activate genes that cause cells to make more collagen, or boost certain repair pathways.

像是水杨酸一类的化学品，可能也能刺激造细胞的基因产生更多胶原，或者是促进某些修复活动的进行。

In addition to activating genes that tell us to stay awake, they make another protein called PER.

除了激活告诉我们保持清醒的基因外，它们还会制造另一种名为 PER 的蛋白质。

When the participants went through winter months, no matter what hemisphere they were in, the lack of sunlight seemed to activate pro-inflammatory genes.

当参与者度过冬季的几个月后，不管他们在哪个半球，缺乏阳光似乎都会激活促炎基因。

And in fact, research has found that the genes that create moveable joints in insects activate on the sides of the body.

事实上，研究发现，在昆虫体内产生可移动关节的基因在身体两侧激活。

Epigenetics—currently one of molecular biology's hottest topics —is a process by which genes are activated or deactivated by the presence or absence of chemical structures called methyl and acetyl groups.

表现遗传学——目前分子生物学最热的话题之一——是这样一个过程，基因的激活或是失效取决于被称为甲基和乙酰基的化学结构的存在或是消失。
