The movement of proteins within the nucleus can occur by diffusion ... The new ways in which cell biology can now be carried out are approaching the mesoscopic scale 15 and surprises are likely ...

After all, there must have been a time when the ancestor of eukaryotes did not possess a nucleus; the question is whether that cell possessed a mitochondrion or not.

Nucleus, cell membrane ... I cut and sell meat over the counter to the public. Biology was probably my favourite subject funnily enough. I've always been fascinated with bodies, with animals ...

For example, how Talin-1 travels to the nucleus and whether sensing mechanical forces is required for its capacity to control gene expression. This discovery in basic cell biology has important ...
