quote:Originally posted by fishytailsThe 'maiden aunt' is a pretty good analogy. really must dig out my Richard Dawkins books again. Are cells programmed so that division is the natural state? it seems like the cell is generally geared up for division until stopped by expression of certain cell cycle inhibitor proteins. mutations in these proteins are what often causes the uncontrolled proliferation in cancer. the 'off' switch is damaged. there is also a lot of cell death, so that all these reproducing cells take the place of all the dying cells, again, much like in a human population. Going back to Richard Dawkins, he takes this even further back and suggests that the genes are the ones that are trying to divide, in this model the actual cell is just an inert carrier.
