A Model for Fluctuating Torque on the Nucleus

12 Jan 2011 | Poster | Contributor(s): Tanmay P. Lele

In living cells, a fluctuating torque is exerted on the nuclear surface but the origin of the torque is unclear. In this study, we found that the nuclear rotation angle is directionally persistent on …
