I was wondering if any new developments have been made concerning centriole function.
I know that centrioles help generate the meiotic and mitotic spindle fiber, which is composed of 9:2 microtubules. I have also heard though, that is some cases, centrioles can be removed from the cell via a laser, and the cell can still produce the spindle fiber.
I know that in Chlaymydons absence of the centriole results in defects but what about in other protozoans and animals cells?
So far I haven’t been able to find anything on Google or Wiki 😯 8) 😆
Higher plants don’t have centrioles because they don’t need them: the microtubules’ self-organizing capibilities are sufficient.Plants form a circular loop of microtubules around the future plane of division prior to prophase called the preprophase band.Also, higher plants do contain microtubule organizing centers which contain many of the same protiens found in animal centrosomes, perhaps the same is happening inside your animal cell for some bizzar reason ❓
