Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the correct order of the 4 phases of mitosis?
A
Telophase, Anaphase, Metaphase, Prophase
B
Prophase, Anaphase, Metaphase, Telophase
C
Prophase, Metaphase, Anaphase, Telophase
D
Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
Explanation: 

Detailed explanation-1: -Stages of mitosis: prophase, metaphase, anaphase, telophase. Cytokinesis typically overlaps with anaphase and/or telophase. You can remember the order of the phases with the famous mnemonic: [Please] Pee on the MAT.

Detailed explanation-2: -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.

Detailed explanation-3: -There are four stages of mitosis: prophase, metaphase, anaphase and telophase. Chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres. Chromosomes line up along the metaphase plate (centre of the cell).
