Detailed explanation-1: -Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells.

Detailed explanation-2: -In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.

Detailed explanation-3: -M phase: Cell division, comprising mitosis, when a fully grown cell segregates the replicated chromosomes to opposite ends of a molecular scaffold, termed the spindle, and cytokinesis, when the cell cleaves between the separated chromosomes to produce two daughter cells.

Detailed explanation-4: -What happens during mitosis? During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.

Detailed explanation-5: -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.
