Meiosis involves two rounds of nuclear division with the daughter cells receiving half the genetic material of the parent, while mitosis involves one. This ensures greater genetic variation.Know More
Both meiosis and mitosis are methods of cell division, and both methods lead to the distribution of genetic material. However, meiosis involves the creation of four daughter cells, each with half the number of chromosomes as the parent. This differs from mitosis, which creates two daughter cells with identical chromosomes.
The reason for this difference is meiosis ultimately leads to sharing genetic material with cells from another organism. As gametes, or reproductive cells, the genetic material received from this exchange will complete the number of chromosomes required. Without the reduction in chromosome numbers, the offspring will have too many when reproduction occurs.
During division, meiosis creates different combinations of genetic material in each of the daughter cells. When compared to mitosis, gametes produced under meiosis will exhibit a range of variation. This also means the eventual offspring from these gametes will be markedly different from the parent.
Meiosis is important as it introduces genetic variation into a species. However, the process also carries the risk of mistakes - for instance, if the cells fail to divide chromosomes equally. Mitosis runs less risk of errors in division occurring as it involves making a replica of the parent cell. However, lack of genetic variation can leave a species more susceptible to disease.Learn more about Molecular Biology & DNA
Mitosis and meiosis are similar in that they are both forms of cellular reproduction, and they both, consequently, produce daughter cells. Both processes also use the same four steps: prophase, metaphase, anaphase and telophase.Full Answer >
Mitosis is important because it is essential for growth and repair in the body. Mitosis happens when a parent cell divides, creating two identical copies, referred to as daughter cells. During this process, it is essential that the daughter cells are exactly the same with the same copies of DNA.Full Answer >
DNA polymerase II is a type of DNA polymerase: a category of enzymes that synthesize identical copies of existing DNA, allowing dividing cells to pass this genetic information on to their daughter cells. DNA polymerase II is found only in prokaryotes, or unicellular organisms, such as archaea, and simple bacteria that lack membrane-bound nuclei and organelles.Full Answer >
The University of Illinois at Chicago explains that DNA must replicate itself so that during cell division, both daughter cells receive the same genetic information. DNA replication is necessary during the process by which somatic cells divide, called mitosis, as well as during meiosis, the process by which organisms produce gametes, or sex cells.Full Answer >
