Detailed explanation-1: -Mitosis consists of five morphologically distinct phases: prophase, prometaphase, metaphase, anaphase, and telophase. Each phase involves characteristic steps in the process of chromosome alignment and separation.

Detailed explanation-2: -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-3: -The cell cycle has two major phases: interphase and the mitotic phase (Figure 6.3). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated and the cell divides.

Detailed explanation-4: -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-5: -M stands for mitosis. This is where the cell actually partitions the two copies of the genetic material into the two daughter cells. After M phase completes, cell division occurs and two cells are left, and the cell cycle can begin again.
