Nuclear Function: Who's in Charge?
What controls a cell? You may have heard that the nucleus is the "brain" of the cell, implying that it's the structure that's in charge.
However, if you take a look at a cell from a functional rather than structural point of view, it becomes very interesting. Structure follows function--if something has a role to do, then it better be built to perform that role--even at the molecular level.
Watch and listen as Professor George Wolfe discusses the magnificent array of the different structures in cells, why their functions are so important, and how these functions act in a collective process in this video from Thinkwell's online Biology series. Who knows, the idea of the nucleus being the brain of a cell just might become an outdated concept.
