MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following has the correct order of phases of mitosis?
A
telophase, metaphase, anaphase, prophase
B
prophase, metaphase, anaphase, telophase
C
metaphase, prophase, anaphase, telophase
D
telophase, prophase, metaphase, anaphase
Explanation: 

Detailed explanation-1: -The correct option is D Prophase-Metaphase-Anaphase-Telophase. Mitotic phase or M phase is divided into four stages. They are: Prophase-The first stage which is marked by the initiation of condensation of chromosomal material.

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: -In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases-G1 and G2, the so-called gap phases-are less dramatic but equally important.
