The Principal Stages of M Phase (Mitosis and Cytokinesis) in an Animal Cell. The five stages of mitosis—prophase, prometaphase, metaphase, anaphase, and telophase—occur in strict sequential order, while cytokinesis begins in anaphase and continues through telophase.
What is the correct order of mitotic phases?
Today, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
What is the correct order of steps in the cell cycle?
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
What is the correct order of these meiotic events?
The correct order of mitotic events which occur during meiosis is: Formation of synaptonemal complex, recombination, separation of homologous chromosomes, separation of sister chromatids.
What occurs in each phase of mitosis?
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope …
What occurs when MPF cyclin levels are highest?
(MITOSIS PROMOTING FACTOR) MPF is a cyclin-CDK complex which acts at the G2 checkpoint which triggers the cells undergo mitosis. (MPF activity corresponds to high levels of cyclin it is active when cyclin concentration is high. … which ensures that daughter cells do not end up with missing or extra chromosomes.
