Cell constriction in bacteria
WebDec 9, 2014 · Cell division is the process by which new cells are made. It is therefore vital for the growth and development, and the regeneration and repair of damaged tissues. When bacterial and animal cells divide, they must constrict their membrane inwards to split a single cell into two. In most bacteria, this constriction is guided by a ring-like structure … WebAsynchronous Constriction. Division can also be asymmetric in a different way: how constricted one side of the cell is relative to the other. You can see that in this Cupriavidus necator cell. Asymmetric constriction is most common early in division, but it sometimes persists longer (⇩). To understand why this happens, we need to take a ...
