If cells in the interphase are subjected to colchicine at which stage will mitosis stop?
Colchicine will stop mitosis at the metaphase stage. Colchicine disrupts the formation of the mitotic spindle fibers, which are critical for separating the replicated chromosomes during mitosis. As a result, cells treated with colchicine will not be able to progress past the metaphase stage of mitosis.
What happens before mitosis begins?
the stage before mitosis is called interphase and majority of the time the cell has is spent in interphase. during interphase the cell acquires nutrients and the DNA replicates.
Is this a correct of false statement- when normal cells stop dividing they always stop after metaphase in mitosis?
Cell division is complete after cytokinesis in which the cytoplasm is divided and there are two complete cells. A cell may enter a period that they will not divide and may never again which is in the Gap 1 phase. It takes certain enzymes to push the cell into S phase and therefore divide again.
What phase do cells stop dividing in?
Cells stop dividing in the G0 phase of the cell cycle, where they enter a resting state. These cells can stay in G0 indefinitely, either temporarily or permanently, depending on external signals or intrinsic factors.
What is the chemical that stops cell division in the metaphase stage?
Colchicine is a chemical that can stop cell division in the metaphase stage by disrupting microtubule formation and preventing the mitotic spindle from forming properly. This results in the cells being arrested at metaphase and unable to progress through mitosis.
The phase of mitosis that ends when the chromosmnes stop moving?
The phase of mitosis that ends when the chromosomes stop moving is called metaphase. In metaphase, the chromosomes align along the cell's equator, and the spindle fibers attach to the centromeres of each chromosome. Once the chromosomes are properly aligned, the cell can proceed to the next phase of mitosis.

What phase are most cells in when they stop dividing?
In between divisions cells enter interphase. During interphase the cell is growing in preparation for the next division. Cells that are no longer dividing are considered to be in senescence. Senescent cells are not growing or replicating their DNA.

When do chromosomes line up at the equator of a cell?
Chromosomes line up with their centromeres on the equator during metaphase of any eukaryotic cell division: mitosis, meiosis I, or meiosis II.During metaphase the arms of the chromosomes are spread out, but it will be the centromeres that lead the way towards the poles during anaphase. This is because in metaphase some spindle fibers, which are formed by the cytoskeleton, attach to the centromeres. It is the contraction of these fibers that pulls the chromosomes (daughter-chromosomes in mitosis and meiosis II) towards the poles in anaphase.There is an important checkpoint during metaphase. If the spindle fibers are not correctly attached, division should stop. However, a few mistakes slip through the net, and sometimes both daughter-chromosomes of a pair (in other words, a pair of former sister-chromatids) move to the same pole. This phenomenon is called non-disjunction, and leads to an abnormal number of chromosomes in both daughter-nuclei.
Which phase comes immediately before the M phase?
Interphase
Is mitosis a way to stop cancer cells from dividing?
No, mitosis is actually the cause of cancer. Well, unregulated mitosis that is. Cancer is basically uncontrolled cell division.
Do fish die if they stop moving?
Fish do not die when they stop moving. Infact, they sleep NOT moving.
What phase(s) of mitosis are chromosomes visible?
InterphaseBefore a cell can enter cell division, it needs to prepare itself by replicating its genetic information and all of the organelles. All of the preparations are done during the interphase. Interphase proceeds in three stages, G1, S, and G2. Cell division operates in a cycle. Therefore, interphase is preceded by the previous cycle of mitosis and cytokenesis. [Diagram showing the cell cycle. The size of the arrows show the relative length of each stage of the cell cycle. Notice mitosis (M) is quite short.]G1 PhaseAfter mitosis is complete the new daughter cell begins to accelerate its biochemical processes which were slowed down by mitosis. The length of the G1 phase creates the difference between fast dividing cells and slowly dividing cells. The G1 phase can be slowed by reducing the nutrients available in a system - thus the cell will take longer to build up the resources necessary for cell division. If there is a severe depletion in nutrients the cells can virtually stop growing. It is interesting to note that cells that aren't growing are always stopped in the G1 phase, being mitotically arrested. This suggests that once the cell enters the S phase, it is committed to cell division, regardless of the external cell conditions.[Animal cell interphase. The DNA has been replicated. Also, notice the increased cell size as the cytoplasm has been enlarged.]S PhaseThe S phase begins with the replication of the cellular DNA. This is described in further detail in DNA replication. When the cellular DNA has been duplicated, leaving the cell with twice as many chromosomes (each chromosome is made up of two identical chromatids), the cell moves onto the G2 phase.G2 PhaseDuring this phase proteins, such as kinase (which catalyzes protein phosphorylation), which are necessary for cell division are synthesized at this time. The chromosome begins to condense and the proteins necessary for construction of the mitotic spindle also are synthesized. When the chromosomes become visible the cell enters the first stage of mitosis, prophase.Continue on to Mitosis 1: Prophase
