Nailing Down HAR Function

A remaining challenge in the study of human accelerated regions (HARs) is establishing their specific functions during development and other biological processes.

By | August 1, 2016

Modern stem cell technologies could provide one way to sttudy human accelerated regions (HARs). Using precision gene editors to change the DNA in a chimp cell to match the sequence of a human HAR, for example, researchers can isolate the effects of that HAR.
