PATHOLOGY

Detailed explanation-1: -Mitosis without cytokinesis results in a cell with more than one nucleus but a connected cytoplasm (syncytium). A multinucleated cell is one with several nuclei. This might be a normal occurrence.

Detailed explanation-2: -During the completion of mitosis (telophase), two new nuclei form around the separated sets of daughter chromosomes (see Figure 8.29).

Detailed explanation-3: -Mitosis and meiosis are similar in that both can only occur in eukaryotic cells. This is because prokaryotic cells do not contain a nucleus within which to begin the processes of mitosis and meiosis. Instead, prokaryotes replicate themselves using binary fission.

Detailed explanation-4: -If a cell underwent mitosis but did not undergo cytokinesis, a single cell with two nuclei containing normal chromosomes will result. During telophase, the nuclear envelope begins to reform prior to cytokinesis. Cytokinesis is the physical splitting of the two cells.

Detailed explanation-5: -If the cell is not grown in the interphase, cells cannot synthesize proteins needed for mitosis. So the process of mitosis cannot be carried in the cells.
