What are the pros and cons of mitosis?
An advantage of mitosis is that it allows your cells to easily replicate and make sister chromosomes. A disadvantage of mitosis is that there is little genetic variation, so each generation is at a risk for the same diseases/disorders.
What is the problem of mitosis?
Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans.
What are some limits to cell division?
Once they reach carrying capacity, they can no longer divide. Some things that control the carrying capacity include food, space, and waste. Since cell division takes energy, bacteria can only divide if there is enough food to support new growth.
What are the 3 limits to cell growth?
What limits cell sizes and growth rates? Cell growth is limited by rates of protein synthesis, by the folding rates of its slowest proteins, and—for large cells—by the rates of its protein diffusion.
What are benefits of mitosis?
Mitosis creates identical copies of the original cells. This allows our skin or our liver to be made of identical cells and allows plants to be able to mass produce leaves with identical properties. Imagine if every one of our skin cells had different DNA!
What is the major disadvantage of mitosis?
Some single cell organisms and some plants do not reproduce sexually through meiosis. Rather, they use mitosis only to make exact copies of their cells. The major disadvantage of this approach is that all of the organisms in a population or all of the plants in an area will have the exact same DNA.
What causes errors in mitosis?
During pregnancy, an error in mitosis can occur. If the chromosomes don’t split into equal halves, the new cells can have an extra chromosome (47 total) or have a missing chromosome (45 total).
What happens if mitosis does not occur?
If there is no mitosis, there would be no cell growth and cell reproduction. Most importantly, genetic information cannot be passed on. All cell functions would be hugely affected.
What would happen if mitosis were uncontrolled?
It is used for growth and repair of different cells. This is also regulated by genes and proteins however when mitosis occurs in an uncontrolled manner, it will replicate the cells rapidly and repeatedly. This will lead to the development of mass of cells or tumor which will later on lead to cancer.
What are the 2 limits to cell growth?
1. The larger the cell, the more demands the cell places on its DNA. 2. The cell has trouble moving enough nutrients and wastes across the cell membrane.
What are the two things that limit cell growth?
Factors limiting the size of cells include:
- Surface area to volume ratio. (surface area / volume)
- Nucleo-cytoplasmic ratio.
- Fragility of cell membrane.
- Mechanical structures necessary to hold the cell together (and the contents of the cell in place)
