Question

What is the purpose of mitosis and meiosis?

Answer 1

Mitosis:

1. Mitosis is a process that separates the genome and ensures that the two daughter cells inherit the same chromosome complement.
2. It is the phase in the cell cycle in which a cell's nucleus gets divided into two nuclei, each with an equal quantity of genetic material.
3. Mitosis is required for cell development and the replacement of worn-out cells.
4. Mitosis is responsible for the zygote's transformation into an adult.

Meiosis:

1. Meiosis is a reduction division in which the parent cell divides into four daughter cells with half the number of chromosomes.
2. The pairing of homologous chromosomes, crossing over, and genetic recombination that occurs during Meiosis I results in two daughter cells with half the number of chromosomes.
3. Meiosis II is similar to mitosis in that it involves the separation of sister chromatids, resulting in four genetically different haploid cells from a diploid parent cell.
4. Meiosis is a cell division process that produces gametes (sperm and eggs) with half the genetic complement of the parent cells.
