PATHOLOGY

Detailed explanation-1: -Cell division occurs during M phase, which consists of nuclear division (mitosis) followed by cytoplasmic division (cytokinesis). The DNA is replicated in the preceding S phase; the two copies of each replicated chromosome (called sister chromatids) remain glued together by cohesins.

Detailed explanation-2: -During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to make two new cells.

Detailed explanation-3: -Mitosis, or M phase, is the period of actual nuclear and cell division during which the duplicated chromosomes are divided equally between two progeny cells.

Detailed explanation-4: -Chromosome duplication occurs during S phase of the cell cycle, whereas most other cell components are duplicated continuously throughout the cycle. During M phase, the replicated chromosomes are segregated into individual nuclei (mitosis), and the cell then splits in two (cytokinesis).

Detailed explanation-5: -Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter-means between, so interphase takes place between one mitotic (M) phase and the next.
