chemical modification

基本解释

In further experiments, they found that removal of these proteins depends on the chemical modification of the GluA1 protein.
在进一步的实验中，他们发现移除这些蛋白质要依赖于GluA1蛋白质的化学改质（chemical modification）。
Other work has focused on histone acetylation, a chemical modification that unwinds DNA from protein spools called histones, thereby enabling gene activity.
其他的工作集中在组蛋白乙酰化，这种化学修饰可以使DNA从组蛋白缠绕中解离出来，产生基因活性。
Mice lacking this chemical modification of GluA1 recovered fear memories induced by loud tones, whereas littermates that still had normal GluA1 protein did not recover the same fear memories.
缺乏这种GluA1化学改质的老鼠会重新出现由响亮的声音造成的恐惧记忆，而同窝出生的老鼠中仍然拥有正常GluA1蛋白质的老鼠不会重新出现相同的恐惧记忆。

They made every minor modification they could to that chemical, and came up with the MLN4670 molecule.
