What would happen if the process of mitosis was out of control?

When mitosis is not regulated correctly, health problems such as cancer can result. The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation. It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells.

What can prevent a cell from undergoing the process of mitosis?

Tumor suppressor genes are segments of DNA that code for negative regulator proteins, the type of regulators that, when activated, can prevent the cell from undergoing uncontrolled division.

What are the effects of chromosomes failing to separate during mitosis?

If chromosomes fail to separate during mitosis, it does not affect the sex cells but a body cell. This mutant body cell then can be reproduced and produce more of the abnormal cells. The cell either dies or is replicated quickly. This could possibly lead to cancer if the cells are not destroyed by the immune system.

What is the end result of mitosis after the cell divides?

The end result of mitosis in humans is two identical diploid daughter cells identical to their parent cell.

What would happen if there were no control points in the cell cycle?

If cells don’t pass the G1 checkpoint, they may “loop out” of the cell cycle and into a resting state called G0, from which they may subsequently re-enter G1 under the appropriate conditions.

What are the possible result from the malfunction of the cell during the cell cycle?

Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms that regulate the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should.

What prevents the plant cell from constricting in the center during telophase?

Telophase and Cytokinesis in Plant Cells In animal cells, cytokinesis gets underway with a simple pinching in of the cell membrane and cytoplasm within by a so-called contractile ring. In plant cells, however, the presence of a cell wall, which most eukaryotes lack, prevents this from happening.

What would happen if there was uneven splitting of chromosomes in anaphase?

During anaphase, sister chromatids (or homologous chromosomes for meiosis I), will separate and move to opposite poles of the cell, pulled by microtubules. In nondisjunction, the separation fails to occur causing both sister chromatids or homologous chromosomes to be pulled to one pole of the cell.

What is the function of mitosis in a cell that is about to divide?

During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

What is the purpose and end result of mitosis?

The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes.

Why is it important for cells to have a control system that regulates cell division?

The control system is responsive to various intracellular and extracellular signals, so that cell-cycle progression can be arrested when the cell either fails to complete an essential cell-cycle process or encounters unfavorable environmental conditions.
