Question

what is mitosis and meiosis​

Answer 1

Answer:

In cell biology, mitosis is a part of the cell cycle when replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the number of chromosomes is maintained.

Answer 2

Mitosis:

Mitosis is a process where a single cell divides into two identical daughter cells (cell division).

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

• During mitosis one cell divides once to form two identical cells.
• The major purpose of mitosis is for growth and to replace worn out cells.
• If not corrected in time, mistakes made during mitosis can result in changes in the DNA that can potentially lead to genetic disorders.

Meiosis:

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.

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 with a parent cell that is diploid, meaning it has two copies of each chromosome.

• These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell divides twice to form four daughter cells.
