What would happen if the spindle fibers did not form in a cell that is undergoing mitosis?
If the spindle fibers did not form in a cell undergoing mitosis, the chromosomes would not be able to properly align and separate during cell division. This could lead to uneven distribution of genetic material, resulting in daughter cells with an abnormal number of chromosomes. This condition, known as aneuploidy, can lead to genetic disorders and cell death. Overall, the absence of spindle fibers would disrupt the precise process of mitosis, potentially causing significant cellular dysfunction.
What else can I help you with?
What would happen if one or more spindle fibers failed to form from one spindle apparatus?
Since spindle fibers are involved in separating chromosomes and centrosomes duringmitosis, you would have impaired mitosis. The spindle is largely made of organized microtubules, which help chromosomes line up during metaphase and then separate during anaphase. The cell has many "checkpoints" which will check to make sure that chromosomes are properly lined up and attached before they can be separated. If the spindle fibers are not properly formed, it would be harder to get past the checkpoint, and so mitosis would be delayed or would not occur at all. If there are mutations in checkpoint proteins (such as in cancer cells), mitosis may proceed but the chromosomes may not be separated normally (resulting in "aneuploidy").They would die because spindle fibers isn't for indiviuals itz mostly dealing with the different phases of mitosis
What do you predict would happen if the spindle fibers were disrupted during the metaphase?
If the spindle fiber were disrupted, the duplicated chromosomes would not be separated.
What structure involved in mitosis in animal cells?
One cell turns into two.A DNA split.Division.It doesn't happen in gametes (sex cells).Mitosis involves the chromosomes to undergo replication and separation in to two identical units to form two daughter nuclei.
When do chromosome duplicate themselves during mitosis?
Chromosomes duplicate during the S phase of interphase, which occurs before mitosis. Each chromosome replicates to form two identical sister chromatids that are held together at the centromere. These sister chromatids are then separated and pulled to opposite poles of the cell during mitosis.
What happens during step 4 of mitosis?
Assuming you follow the PMAT process of mitosis, stage four is telophase.Telophase is the end phase of mitosis, and coincides with mid-cytokinesis. During this phase, a number of events happen:1. the spindle fibres break down, along with the astral rays as the centrioles become inactive.2. A new nuclear membrane forms around the chromosomes, at opposite sides of the cell.3. The chromosomes lengthen, becoming chromatin. Nucleoli may also be present at the end of telophase.After telophase, the cell re-enters interphase, starting with growth phase 1.

What happen before prophase occur?
During prophase, the chromatin fibers present in the nucleus coil tightly into observable chromosomes. The centrosomes move away from each other and spindle microtubules begin to grow from them; this marks the formation of the mitotic spindle.

Explain why prophase is the longest phase in mitosis?
because the most things happen in it. centrioles grow, spindle fibers arrange on chromosomes, and the cell grows exponentially.
What two things happen during Metaphase?
During metaphase in mitosis or meiosis, the chromosomes align at the cell's equator in a single file line and the spindle fibers attach to the centromeres of the chromosomes, ensuring they are positioned correctly for separation in the next phase.
When do chromosome duplicate themselves during mitosis?
Chromosomes duplicate during the S phase of interphase, which occurs before mitosis. Each chromosome replicates to form two identical sister chromatids that are held together at the centromere. These sister chromatids are then separated and pulled to opposite poles of the cell during mitosis.
What would happen if there were no spindle checkpoints?
If there were no spindle checkpoints then the chromosomes wouldn't be in the right position for the reproduction of the cell.
What exactly happens in phase 4?
Phase 4 of cardiac action potential involves rapid ventricular repolarization, as the potassium channels open and potassium ions flow out of the cell. This leads to the restoration of the resting membrane potential. The cell is then ready for the next cycle of depolarization and contraction.
What is telophase's job?
Fourth step in mitosis where three things happen 1)nuclear membrane comes back 2)chromosomes turn into chromatids 3)spindle falls apart. :)
What would happen if our cells did not go through mitosis?
We would probably be in a lot of trouble if we didn't have mitosis! In fact, we probably wouldn't exist at all. From the time an egg is fertilized by a sperm, mitosis starts to happen. And in our daily lives, skin cells, stomach cells, hair cells, bone cells, and other tissue cells are undergoing mitosis!
Where in the body cell does Mitosis happen?
Mitosis occurs in the Nucleus.
