What is the process between one mitosis and the next?
Cytokinesis
What is the formation of 2 cells from one existing cell?
It is the process of mitosis followed by cytokinesis.
Do human cells undergo mitosis and cytokinesis?
No. There are certain organisms that do not go through cytokinesis and the resulting phenomena is that the organisms cells will contain more than one nucleus (aka multinucleated)
How do cell that do not undego cytokinesis differ in appearance from cell that do undergo cytokinesis?
Cells that do not undergo cytokinesis will have multiple nuclei, while cells that do undergo cytokinesis will have only one nucleus.
The three stages of the cell cycle?
1. Interphase is the period between divisions when nothing seems to be happening. 2. Nuclear Division is when the genetic material is dividing and you can see the chromosomes. As you know eukaryotic cells have two types of nuclear division - mitosis and meiosis. Therefore this is often called M phase. During M phase one mother nucleus becomes two daughter nuclei. 3. Cytokinesis divides the cytoplasm of the mother cell into two daughter cells and this is very obvious under the microscope. It is during cytokinesis that one mother cell becomes two daughter cells.
What is the relationship between the processes of mitosis and cytokinesis?
Mitosis is the division of the nucleus, and cytokinesis is the division of the cytoplasm. Cytokinesis begins during telophase, and, unlike mitosis, occurs different in plants and animals. In plants, cytokinesis occurs when a new cell wall or cell plate forms between the two, newly formed nuclei. In animals, a cytokinesis is characterized by the formation of a cleavage furrow produced by contractile rings made up of microfilaments. (Campbell, and Reece 227). Cytokinesis would be a pointless process if not for mitosis because mitosis creates two daughter cells. If there weren't two fully formed nuclei by telophase, the cell would split and one "cell" would be left without a nucleus, and therefore useless. Although, by definition , mitosis may occur without cytokinesis, the two daughters must be separated in order to function properly and most efficiently.
What are the stages of mitosis and cytokinesis?
Mitosis and cytokinesis are elements of cell division. Mitosis is the duplicated genome in the cell is divided into halves which are identical. Cytokinesis is the where the cytoplasm of the cell divides to form two daughter cells.
Can mitosis occurs in a cell in the absence of cytokinesis Support your answer If your answer is yes provide a description of how the new cell would appear in the G1 phase of the cell cycle?
Yes. mitosis is nuclear division whereas cytokinesis is cell division. The result would be one cell with 2 nuclei
The importance of mitosis and cytokinesis in the life cycle of a eukaryotic cell?
Mitosis is the division of the nucleus of a cell. Cytokinesis is the division of the cytoplasm of a cell to create two separate cells. In order for cells to divide to form daughter cells both processes are needed. Mitosis occurs creating two genetically identical nuclei and cytokinesis completes cell division resulting in the two genetically identical eukaryotic cells. One of the nuclei is in each cell.
What is two main phases one in witch the cell lives and carries out its functions and one in witch the cell divides?
Interphase and mitosis followed by cytokinesis.
What cell is not in a phase of mitosis?
The phases of Mitosis are Interphase, Prophase, Metaphase, Anaphase, Telophase (IPMAT). Cytokiensis is a separate thing altogether from Mitosis. So anything other than IPMAT is "not a phase in mitosis".
Why mitosis has to come before cytokinesis in the cell cycle?
The most probable solution is that Mitosis requires alot of energy as well as a lot of nutrients to go through the process. Since Interphase is the beginning stage, the G1, S and G2 phases come into play and help create nutrients and energy.
