The kinetochore microtubules shorten as the chromatids are pulled toward opposite poles, while the polar microtubules subsequently elongate to assist in the separation. Anaphase typically is a rapid process that lasts only a few minutes, making it the shortest stage in mitosis.

Which of the phases of mitosis has the shortest duration?
The stage taking the least amount of time in mitosis is anaphase.
Where in your body does mitosis occur most often?
mitosis occurs most often in the skin where cells die frequently and blood since red blood cells die everyday. Areas such as the brain where cells last way longer and don't get damaged is where mitosis occurs the least
Write a hypothesis about what you think would happen if cyclin were injected into a cell that was in mitosis?
The cell's process of mitosis would be accelerated or at least stimulated due to the bonds of each the cyclin proteins.
What stage in mitosis does cell spend the most time in?
MitosisIntroductionThere are five main phases of Mitosis, plus one that is included to certain cell types.They are listed in order from:InterphaseProphaseMetaphaseAnaphaseTelophaseCytokinesisPrecursor to MitosisBefore mitosis is the phase in the cell cycle called interphase. This takes up 78% of the time in a cell's division cycle, and is the longest phase in the cycle.Interphase consists of the three subphases called G1, Synthesis, and G2.Prophase14% of the time in a cell's cycle is spent in the prophase.This is the second longest phase in the cell cycle, but the longest phase in actual mitosis. In prophase, the DNA supercoils into chromosomes, the nuclear membrane breaks down, and the centrioles move towards the opposite poles of the cell. The spindle microtubules also assemble.Metaphase4% of the time in a cell's cycle is spent in the metaphase.In metaphase, the spindle microtubules then attach to the centromeres of the chromosomes and the chromosomes then line up along the equator of the cell.Anaphase0.8% of the time in a cell's cycle is spent in the anaphase.This is the shortest phase in the cell cycle. In anaphase, the spindle microtubules shorten, the sister chromatids (two individual chromosomes paired and attached at the centromere) split into two identical chromosomes. The chromosomes are then pulled to the opposite poles of the cell proportionately.TelophaseRoughly 3% of the time in a cell's cycle is spent in the telophase.In the telophase, the chromosomes then unwind at their poles, the spindle microtubules break down, and the nuclear membrane reforms.Cytokinesis (Not a separate phase)Cytokinesis occurs at the end of the cycle, but is not actually a phase. This step either occurs during telophase or never occurs at all, in which case the cell fails to divide. In cytokinesis, the cytoplasm divides into two.
Where in the human body does mitosis take place?
Mitosis takes place in our bodies mainly to repair things like our skin cells (which are constantly shedding and being repaired) and damaged cells in our body as well as organ tissues. Mitosis is a form of ASEXUAL reproduction which occurs in plants when they reproduce (only one parent is involved). This is why parent plants are all identical to their offspring as there is no variation in genes. This is because ALL of the genes are passed from that one parent onto their offspring so the offspring fully resemble the parent. However, as humans, we have 46 chromosomes and cannot have a baby ourselves. Therefore, the process of Meiosis (sexual reproduction) takes place. When the sperm fertilizes the egg, only 23 chromosomes go to the egg and 23 of the mother's chromosomes go to the egg, making 46 chromosomes in total. Therefore, only HALF of the mother's and father's chromosomes are donated to the offspring causing variation. This is why their offspring never fully resemble one parent and no two offspring resemble each other genetically - unless they're twins! (but yet still, their fingerprints differ.) Therefore, Mitosis is a form of asexual reproduction and Meiosis is sexual reproduction. Both are extremely vital to us. Mitosis is therefore, very useful in itself as in humans, it does not contribute in the process of reproduction, but helps in repairing our body tissues and cells which is extremely vital.

What phase of mitosis in animal cell is least amount of time?
t phase
Why parenchyma is least specialised tissue?
Because it is a cluster of cells just created by mitosis
Processes is least likely to introduce variations into the genetic make-up of a population?
Mitosis
Can cells be observed with magnifying glass?
No, you have to use a Electromagnetic telescope at least
In which stage of the cell cycle does a cell spend the least of its life?
it would be Metaphase and Anaphase if you do a lab on it like we did in class. interphase has 7 cells 7/17=41% prophase has 4 cells 4/17=23% metephase has 1 cell 1/17= 6% anaphase has 1 cell 1/17= 6% telophase has 2 cells 2/17=12% cytokinisis has 2 cells 2/17=12%
In a 40-day period, at least one bear was observed by a camper in a designated camp site on 28 separate days. According to this information, what is the daily frequency of bear sightings (in which at least one bear is observed)?
28% (apex)
What is the third most frequently used letter in English?
"A" is the 3rd most frequently used letter. "T" is 2nd, and "E" is 1st. The least frequently used letter is "Z."

The cell's process of mitosis would be accelerated or at least stimulated due to the bonds of each the cyclin proteins.
What types of cells in your body are no longer going under mitosis?
Nerve cells - or at least very slowly.
Which type of reproduction results in the least amount of genetc variation?
Mitosis to produce a larger population
