Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The longest phase of the cell cycle
A
prophase
B
interphase
C
metaphase
D
mitosis
Explanation: 

Detailed explanation-1: -Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter-means between, so interphase takes place between one mitotic (M) phase and the next.

Detailed explanation-2: -The longest stage of interphase is G2. The given statement is “false”. The interphase and the mitotic (M) phase are the two main cell cycle stages in eukaryotic cells. The cell grows and duplicates its DNA during the interphase phase of the cell cycle.

Detailed explanation-3: -The first and longest phase of mitosis is prophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope (the membrane surrounding the nucleus) breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell.
