The G0 phase describes a cellular state outside of the replicative cell cycle. Classically, cells were thought to enter G0primarily due to environmental factors, like nutrient deprivation, that limited the resources necessary for proliferation. Thus it was thought of as a resting phase. G0 is now known to take different forms and occur for multiple reasons. For example, most adult neuronal cells, among the most metabolically active cells in the body, are fully differentiated and reside in a terminal G0 phase. Neurons reside in this state, not because of stochastic or limited nutrient supply, but as a part of their internal genetic programming.
Interkinesis or interphase II is a period of rest that cells of some species enter during meiosis, between meiosis I and meiosis II.[1][2]No DNA replication occurs during interkinesis, however it does occur during the interphase I stage of meiosis (See meiosis I). During interkinesis the single spindle of the first meiotic division disassembles and the microtubules reassemble into two new spindles for the second meiotic division.[3]Interkinesis follows telophase I and is where Many plants skip telophase I and interkinesis, going immediately into prophase II. Each chromosome still consists of two chromatids.
