Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the first thing that happens during mitosis?
A
The chromosomes line up along the middle of the cell
B
The sister chromatids separate
C
The DNA condenses and the nuclear membranes break down
D
The cytoplasm divides
Explanation: 

Detailed explanation-1: -At the beginning of mitosis, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down, resulting in the release of most of the contents of the nucleus into the cytoplasm.

Detailed explanation-2: -Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process that will continue until metaphase.

Detailed explanation-3: -Prophase is the first step of mitosis, during which chromosomes condense and the nuclear envelope dissolves. Metaphase follows prophase.

Detailed explanation-4: -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.

Detailed explanation-5: -Prophase. Figure 1: During prophase, the chromosomes in a cell’s nucleus condense to the point that they can be viewed using a light microscope. Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell’s nucleus condense and form tight structures.
