Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The following describes ____ during mitosis. The chromatin condenses and spindle fibers form at each side of the cell. The nuclear membrane breaks apart.

A	prophase
B	metaphase
C	anaphase
D	telophase

Explanation:

Detailed explanation-1: -Prophase. The first and longest phase of mitosis is prophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down . In animal cells, thecentrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell.

Detailed explanation-2: -Prophase is the first stage of mitosis. In prophase, chromosomes condense and become visible. spindle fibers emerge from the centrosomes.

Detailed explanation-3: -During prophase, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down.

Detailed explanation-4: -During telophase, the chromosomes arrive at the cell poles, the mitotic spindle disassembles, and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes.
