What are some reasons why a cell would undergo cytokinesis?
It is the last stage in mitosis and meiosis so it must occur for a cell to split into two daughter cells
What are the two reasons you need mitosis in your bodies?
-To replace missing cells -To replace dead cells
How are mitosis and meiosis simlair?
Meiosis and Mitosis are both the division of something. Meiosis is the division of chromosomes and Mitosis is the division of cells. They both occur in the cell cycle. Meiosis creates 4 daughter cells and Mitosis creates two complete cells.
Does mitosis refer to nuclear division and NOT cytoplasmic division?
No. The aim of mitosis is the creation of two, new, daughter cells and this does not occur without chromosomal migration, cytokinesis, and furrow formation and completion. Good ?n.
Where in the skin does mitosis occur?
Mitosis occurs in the basal surface of the skin. This can also take place in the epithelium so as to replace damaged tissues of the skin.

What two processes occur when a cell with a distinct nucleus divides?
Mitosis and Cytokinesis
When does cytokininesis occur in animal?
It take place after mitosis. It pinches cell into two.
What are the two process that closely occur in mitosis?
Replication of DNA and separation of sister chromosomes.
What two factors would cause mitosis to occur in an onion plant?
Water and light
Explain why DNA replication must occur before mitosis starts?
DNA replication mus occur before mitosis starts. Mitosis is another word for cell division and so there must be two copies of DNA for each cell at the end stage.
What are the two reasons you need mitosis in your bodies?
-To replace missing cells -To replace dead cells
How many rounds of chromosome replication occur in the cell?
how many rounds of chromosome replication occur i the cell pirior to mitosis
What are two reasons that cell undergo mitosis and divide?
so that a multicellular organism can grow and have more cells
Why does crossing-over not occur in mitosis?
well from what i understand mitosis is just the replication of a cell, a cell divides into two cells and it is not being effected by any other cell so crossing over cant occur Crossing over occurs in meiosis to create diversity in the genetic material so the offspring is neither identical to father or mother. in mitosis it does not occur because the parent cell is making an identical copy of itself, so the DNA does not need to vary.

Differences between mitosis and meiosis?
place of occurence ;mitosis= somatic cells | meiosis=gonadic cells crossing over;mitosis=does not occur | meiosis=occur during prophase of meiosis 1 to form tetrads number of daughter cell;mitosis=two | meiosis= four genetic variation;mitosis=no variation produced| meiosis=produces genetic variation genetic composition in daughter cell; mitosis=identical to the parent cell | meiosis= non identical to the parent cell and each other
