What would happen if the spindle fibers did not form in a cell that is undergoing mitosis?

If spindle fibers failed to form in a cell during division, both daughter cells would become non-viable shortly after division. The spindle fibers pull one set of chromosomes into each of the daughter cells, so without them there cannot be an equal division of genetic material.

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.
When do chromosome duplicate themselves during mitosis?
In Mitosis, the chromosomes duplicate themselves. In Meiosis 1, they duplicate, however they do not duplicate in meiosis 2.
What happens during step 4 of mitosis?
During step 4 of mitosis, known as anaphase, the sister chromatids separate and are pulled to opposite ends of the cell. This is facilitated by the spindle fibers contracting, causing the chromatids to move towards the centrosomes. Once the sister chromatids are fully separated, they are considered individual chromosomes.
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.
What exactly happens in phase 4?
There are many things that happen in phase 4 of Mitosis. In phase 4 of Mitosis, the prophase chromosomes separate into pairs. Spindle fibers begin to form.

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.
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!
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 - the second stage of mitosis in the eukaryotic cell cycle - the chromosomes, pulled by the spindle fibers, line up along the middle of the cell, halfway between the centrosomes in the middle of the dividing cell. The chromosomes are now maximally condensed. In mitosis, individual replicated chromosomes, each composed of two sister chromatids, move to the equatorial plate during this step (whereas during the first division of meiosis, pairs of replicated chromosomes (tetrads) line up at this stage). This lack of pairing between homologs during mitosis is a fundamental distinction between mitosis and meiosis. Mitosis, unlike meiosis, produces identical daughter cells, because each homolog divides into two identical chromatids during anaphase.
What will happen to chromosomes that has two centromere?
centromere is place at which spindle fibers are attached if the centromere is lost then chromosome will lose its point for the attachement of the spindle fiber and then will not be able to take part in mitosis. chromosome is usually lost in this case.
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. :)
Name four things that happen during telophase?
1:Chromatids are pulled to opposite poles of cell. 2:Nuclear Envelope and Nucleolus reform. 3:Chromosomes uncoil. 4:Spindle Fibers disintegrate.
Where in the body cell does Mitosis happen?
Mitosis occurs in the Nucleus.
