Stages of Cell Division
· Length of time varies between cell type, species and availability
of nutrients
· Divided into stages-
­ Interphase ­ DNA Replication
­ Mitosis ­ Nuclear division and chromatids seperate
Divided into Prophase, Metaphase, Anaphase, Telophase
­ Cytokinesis ­ Cell cleavage
­ Growth Phase
· All daughter cells also need new cell organelles to be created…read more
