MICROANATOMY

Detailed explanation-1: -The timing of DNA synthesis thus divides the cycle of eukaryotic cells into four discrete phases (Figure 14.1). The M phase of the cycle corresponds to mitosis, which is usually followed by cytokinesis.

Detailed explanation-2: -1 M Phase. The M phase consists of mitosis and cytokinesis. Mitosis is the process in which DNA condenses into visible chromosomes, which is followed by the separation of the chromosomes into two identical sets.

Detailed explanation-3: -During mitosis (nuclear division), the chromosomes condense, the nuclear envelope of most cells breaks down, the cytoskeleton reorganizes to form the mitotic spindle, and the chromosomes move to opposite poles. Chromosome segregation is then usually followed by cell division (cytokinesis).
