Detailed explanation-1: -In mitosis, the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle, a specialized structure made out of microtubules. Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase.

Detailed explanation-2: -Mitosis steps consist of prophase, metaphase, anaphase, and telophase; the cell undergoes nucleus division and split into two identical daughter cells. The stages of mitosis occur in sequence with specific events in each one. By observing the chromosome, one can identify the mitotic process.

Detailed explanation-3: -As the third phase-anaphase-begins, the chromatids separate and move to opposite ends of the cell. Once the chromatids separate, they are called chromosomes. In this way a complete set of chromosomes migrates toward each centriole. In the last phase-telophase-the cell divides.

Detailed explanation-4: -A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Detailed explanation-5: -These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
