Mitosis is made up of how many phases?
A
4
B
5
C
6
D
7
Explanation: 

Detailed explanation-1: -Mitosis consists of five morphologically distinct phases: prophase, prometaphase, metaphase, anaphase, and telophase .

Detailed explanation-2: -These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.

Detailed explanation-3: -The stages of Mitosis are: Prophase – The chromosomes shorten and thicken. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids break apart at the centromere and move to opposite poles. Telophase – Two nuclei formed after nuclear envelopes reform around each group of chromosomes.

Detailed explanation-4: -The cell cycle is usually divided into four main phases. The first three phases are often referred to as the interphase, and they prepare the cell for the fourth phase-mitosis.

Detailed explanation-5: -Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
