A simple example is diffusion in one dimension with an impermeable boundary; this constrains the otherwise random walks, leading to a nonrandom distribution of particle positions relative to the boundary. A more complicated case, that is directly relevant to biology, is the case in which the ...

In cells that undergo an open mitosis,prometaphasebegins abruptly with disassembly of thenuclear envelope(Fig. 44.5). Microtubules growing outward from the spindle poles penetrate holes in the nuclear envelope, make contact with the chromosomes, and attach to them at specialized structures calledkinetoc...

One simple model that explains why bivalent spindles are maintained in a structurally stable manner at the spindle equator during metaphase is that two opposing but balanced forces are operational. One force is derived from sister chromatid cohesion, which acts as a glue and is required for the ...
Positions of putative destruction boxes (D boxes) in Xkid are shown as small boxes. Cdc2 phosphorylation consensus sequences are marked with asterisks. HhH1 and coiled-coil domains predicted by simple modular architecture research tool (SMART, http://smart.embl-heidelberg.de) are indicated with ...
The combination of all these forces results in chromosome movements that culminate with their alignment on the metaphase plate in a process called congression (37, 31). Forces acting at kinetochores are, at least in part, generated by microtubule dependent motors localized at kinetochores. One of...
