Both Hudson tomcod and New Bedford killifish, however, have unusual AHR molecules.

哈德逊鳕鱼和新贝尔福德鳉鱼都拥有特殊的AHR。

AHR is a transcription factor, meaning that it controls the process by which messenger molecules are copied from genes.

AHR的是一种转录因子，也就是说，它控制的信使分子的基因复制过程。

The shortened version of AHR does not bind nearly so easily to PCBs. It still, however, seems to work as a transcription factor.

这个缩减版本的AHR难以和PC B结合，不过看来依然能发挥转录因子的作用。

The result is the culmination of a two-year research project called the Autonomous High Altitude Refuelling (AHR) programme.

The shortened version of AHR does not bind nearly so easily to PCBs.

PCBs do their damage by binding to a protein called the aryl hydrocarbon receptor, or AHR, thus stopping it working properly.
