Understanding Mitosis

Mitosis begins with DNA coiling into chromosomes. Spindles form from centrioles, and the nuclear membrane disintegrates. Chromosomes align at the cell center, and chromatids are pulled to opposite poles. The process concludes with the reformation of nuclear membranes and cell division, sustaining life.

What initiates the formation of chromosomes during mitosis?

• The separation of cytoplasm

• The disintegration of the nuclear membrane

• The unwinding of chromosomes

• The coiling of DNA threads

What role do protein fibers play during the early stages of mitosis?

• They separate the cytoplasm

• They form a network of spindles

• They unwind the chromosomes

• They disintegrate the nuclear membrane

How do spindles contribute to chromosome movement?

• By coiling DNA threads

• By forming a new nuclear membrane

• By attaching to chromosomes and pulling chromatids

• By separating the cytoplasm

What happens to the chromosomes after the cell stretches?

• They merge into a single structure

• They disintegrate

• They continue to coil tightly

• They unwind and nuclear membranes reform

What is the final result of mitosis?

• Protein fibers dissolve

• Two new cells are created

• Chromosomes coil into DNA threads

• The nuclear membrane disintegrates
