Why is the study of mitosis and meiosis important in the field of biology?

Answer 1

The study of meiosis and mitosis has many implications for human medicine. Defects in meiosis, known as nondisjunction, will result in sperm or eggs having two many or two few chromosomes, a condition known as aneuploidy. For example, a gamete having an additional chromosome 21, when fused with another gamete having one chromosome 21 will result in a child having three chromosome 21s, resulting in Downs Syndrome. Turner Syndrome results from the lack of a sex chromosome (such as in an XO individual.) There are numerous other examples. Most aneuploid conditions are lethal. The study of mitosis is very important because defects in mitosis are very common in cancers. These problems in mitosis can lead to cells dividing when they shouldn't be dividing, leading to overgrowth of the cells. Many cancer cells show this property of unregulated growth and division because they are mutated in those genes which control mitotic checkpoints. Intrinsically, the study of mitosis and meiosis is important at a scientific /biological level because of its sheer complexity and importance at a fundamental level -- all cells have to divide and reproduce. When you consider the number of proteins and structures that need to be choreographed, like the spindle, the kinetochores, and chromosomes, the cytoskeleton, and the regulation of all these things, these processes are incredibly fascinating. I hope I've inspired you to study more about mitosis and meiosis!

Answer 2

Mitosis and Meiosis both have to do will cell replication and genetic reproduction. Since biology has a lot do with the study of living organisms, reproduction would be pretty important for a species to survive.

Answer 3

Why Is Meiosis Important

Answer 4

Mitosis and meiosis both have to do with passing on the right amount of DNA. Can't get much more important than that.

Answer 5

mitosis and meiosis are different ways the cell divides. cellular division is the basis of life if there was no cellular division we would have died and never developed from a zygote. there are many problems with human health that has to do with rate of cellular division. For example winkling, there is theory that as a person ages the rate of cellular division decreases and the skin does not have enough cells replacing it, therefore the skin looses elasticity and as a result wrinkles. we need to study cellular division to better understand diseases such as cancer, uncontrollable division of mutated cells. we need to understand this in order to fight these problems. there are many other reasons and other more directed toward meiosis.

Answer 6

mitosis and meiosis deal with cell division, and cells are the base of all living things. mitosis divides into 2 daughter cells that's essential for the survival of organisms, and meiosis create sex cells, the pass down of genetic material from the parent to offspring. all these are essential to bio.

Answer 7

this is how genetic information is passed on to new cells
