Mechanism that unwinds DNA may function similar to an oil rig ‘pumpjack’

DNA is unwound by a type of “pumpjack” mechanism, similar to the way one operates on an oil rig, a team of scientists suggests. This finding is based on new close-up images of the proteins that unwind DNA inside the nucleus of a yeast cell and could offer insight into ways that DNA replication can go awry and trigger disease. —> Read More
