WebThe DNA molecules must be packed into an incredibly compressed and compact structure called chromatin in order to fit into the nucleus. The DNA is reduced to an 11 nm fibre during the earliest phases of packaging, which represents approximately 5-6 folds of compaction. This is accomplished by packaging nucleosomes in a specific order. WebAll eukaryotic cells undergo a cell cycle from beginning to end. This starts with interphase, which is subdivided into G1, S and G2. The following M phase has mitosis (which has the cell division stages prophase, metaphase, anaphase and telophase) and cytokinesis to close out the cell cycle.
