Meiosis is a cell division process that occurs twice to produce four haploid daughter cells, according to Biology4Kids. Meiosis I occurs first and creates two daughter cells, and then meiosis II begins and creates two more daughter cells.
Meiosis is a cell division process that occurs when an organism is ready to reproduce, states Biology4Kids. The steps of meiosis are similar to the steps of mitosis, another type of cell division that occurs during growth and development of an organism. Meiosis begins with meiosis I. During this process, the cell undergoes prophase, metaphase, anaphase, telophase and interphase and creates two haploid daughter cells. Haploid cells contain only half of the number of chromosomes an organism needs to survive.
During meiosis I, crossing over occurs within the DNA. Crossing over allows genes to cross over to other chromosomes and mix themselves up, explains Biology4Kids. It is a process that adds diversity and variability to the gene pool of the organism. During meiosis II, the cells from meiosis I undergo prophase, metaphase, anaphase and telophase. After telophase of meiosis II, the cells begin to pinch inward and separate. At the end of meiosis II, there are four haploid cells known as gametes.Learn More
Skin mitosis is the process by which skin cells divide, creating new skin cells for wound repair and skin renewal. Unlike in other types of cells, mitosis occurs constantly in healthy skin cells, according to NCBI.Full Answer >
As explained by DevBio, nondisjunction is what happens when a pair of chromosomes do not separate properly during meiosis. According to Indiana University-Purdue University Indianapolis (IUPUI), nondisjunction can occur during either anaphase I or anaphase II of meiosis.Full Answer >
As BBC explains, the main purpose of microvilli is to increase the surface area of the small intestine. With larger surface area, nutrients from food are more readily absorbed into the blood.Full Answer >
The mitochondria inside a cell produces ATP, or adenosine triphosphate. Cellular respiration is responsible for ATP production, a process in which ATP production occurs after biochemical energy from nutrients is converted.Full Answer >
