What are four phases mitosis?

Answer 1

1. Prophase: The genetic material in the nucleus condenses and the duplicated chromosomes become visible. The nucleolus disappears and the nuclear envelope begins to break down, spindle fibers also start extending from both poles of the cell.
2. Metaphase: The duplicated chromosomes become aligned in the center of the cell, spindle fibers attach themselves to the centromere of the chromosomes.
3. Anaphase: The stage of mitosis in which the duplicated sets of chromosomes separate and two identical groups move to opposite poles of the cell.
4. Telophase: A nuclear membrane re-forms around each new group of chromosomes

Answer 2

Prophase-chromatin condenses into chromosomes which are in pairs, cenrtioles start to split apart and move towads separtate poles and the nuclear eveolope dissolves. Spindle fibers begin forming. Metaphase- the chromosome pairs line up at the center or "equator" of the cell and spindle fibers attach. This pulls the chromosomes, now split apart called the sisiter chromatids. It can be remembered by this Metaphase Middle. Anaphase-Spindle fibers pull the sister chromatids apart. The sister chromatids start to move towrads the poles and move towards the poles. (This ends immedialtly when they reach the poles.) Telophase-the sister chromatids (which are the chromosomes that got pulled apart by the spindle fibers in the phase-Metaphase) reach the poles. A nuclear envolpe forms around them. Two cells form. Then cytokinesis occurs. Cytokinesis is the actual pinching off of the cytoplasm and the plasma membrane(also called the cell membrane). Cytokniesis happens during telophase but is a different process.

Answer 3

The four stages of mitosis are, prophase metaphase, and anaphase, and telophase. Prophase is the longest and first phase during mitosis, it takes about 50 to 60 percent of the time. During the phase the chromosomes become visible. The centrioles are two tiny structures located in the cytoplasm. Metaphase is the second phase of mitosis that only lasts a few minutes. During this phase the chromosomes line up across the center of the cell. Anaphase is the third stage of mitosis. During anaphase, the centromeres that join the sister chromatids split; allowing the sister chromatids to separate and become individual. The final stage of mitosis is telophase. The chromosomes, which were distinct ad condensed, begin to disperse into a tangle of dense material. A nuclear envelope re-forms around each cluster of chromosomes.

Answer 4

FIRST OF ALL THERE ARE MORE THAN 4 PHASES IN MITOSIS. 1. INTERPGASE 2.PROPHASE 3.PROMETAPHASE 4.METAPHASE 5.ANAPHASE 6.TELOPHASE 7.CYTOKINESIS THOSE ARE THE PHASES OF MITOSIS. No, there are only FOUR phases of mitosis. The phases listed above are all of the phases of the cell cycle. The four basic phases of MITOSIS are PROPHASE, METAPHASE, ANAPHASE, and TELOPHASE.
