What is prophase in simple words?
1 : the initial stage of mitosis and of the mitotic division of meiosis characterized by the condensation of chromosomes consisting of two chromatids, disappearance of the nucleolus and nuclear membrane, and formation of mitotic spindle.
What is prophase example?
For example, human beings have 23 pairs of chromosomes in all somatic cells, or 46 chromosomes in total. At the end of prophase, each of these 46 chromosomes contains two identical chromatids. One of the two stages in meiosis that resemble prophase in mitosis.
What is called meiosis?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. … Meiosis begins following one round of DNA replication in cells in the male or female sex organs.
What is the other name of meiotic cell division?
Explanation: The other name for meiotic division is reduction division because the number of chromosomes are reduced to half. If there are 46 chromosomes in mother cell then there will be 23 chromosomes in the daughter cell after meiosis i.e. the reduction division.
Is meiosis and meiotic the same?
In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells, each with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as meiosis I and meiosis II.
Comparison to mitosis.
|Genetically same as parent?||No||Yes|
What is mitotic division also known as?
1. The process in cell division by which the nucleus divides, typically consisting of four stages, prophase, metaphase, anaphase, and telophase, and normally resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes. Also called karyokinesis.
What is the opposite of mitosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
