Cell Division

Ok. That makes more sense. Thanks.

Someone correct me if I'm wrong but as much as I know not all organelles replicate themselves. The ones which have its own genetic material can replicate. For example: mitochondria, chloroplasts, centrioles, ribosomes.
The other ones are sythesized before the division starts. For example; lysosomes.

huh? wait a sec, please answer this question as i need to do a presentation on centrioles on monday:
do centrioles have their own dna? and if they don't, is there an actual scientific explanation as to how they are able to self replicate?
I thought they didn't have their own DNA, and that there are no proved explanation...can any clarification be offered to me?

no, centrioles do not have any DNA, but they grow and split into two new during the cell cycle
