Mitosis is the scientific term for nuclear cell division, where the nucleus of the cell divides, resulting in two sets of identical chromosomes. Mitosis is accompanied by cytokinesis in which the end result is two completely separate cells called daughter cells. There are four phases of mitosis: prophase, metaphase, anaphase and telophase. The first phase of mitosis is prophase. In this phase the chromosomes which are normally spread throughout the nucleus begin to Condense. The DNA molecules of the chromosomes begin to interact with enzymes and proteins that carry-out the replication of the genes. The compact coiling of the chromosomes {around histone protein cores} at this stage of mitosis is prepares the chromosomes for the next phase. Nearing the end of prophase, the nuclear enclosing 'nuclear envelope' and the cytoskeleton disappears. The cytoskeleton is transformed into what is called a spindle apparatus which works to pull the duplicated chromosomes apart during the anaphase.
The second phase of mitosis is metaphase. In this phase the chromosomes of the dividing cell begin to line up and are coordinated with the spindle apparatus. The soon to be divided chromosomes are symmetrically positioned on the metaphase plate typically at the equator of the parent cell.
Anaphase is the third step of mitosis. Abruptly the spindle apparatus pulls the two identical sets of chromosomes apart from one another. Each new set of chromosomes is moved to opposite spindle poles. These two sets of chromosomes will soon develop into the nuclei of two daughter cells perfectly identical to each other as well as identical to the parent cell.
The final stage of mitosis is telophase which means end. Telophase is best described as the opposite of prophase. As the chromosomes begin to move toward the spindle pole they start to uncoil and spread out. Then the spindle apparatus made of the former cytoskeleton is deconstructed. Finally the nuclear envelope or membrane is formed around the chromosomes. Although this is the last phase of mitosis, telophase will not be complete until cytokinesis has been carried out. Cytokinesis is similar to mitosis except it involves the cell's cytoplasm and organelles, where mitosis is the division of the nucleus or control center of the cell. Once mitosis and cytokinesis are properly completed there are two new functioning Cells.

5 different between mitosis and meiosis and 5 same between mitosis and meiosis give me a list plz?
Differences: # Cells undergoing mitosis divide once, cells undergoing meiosis divide twice. # Mitosis is for cell replication, meiosis is for genetic recombination and to produce reproductive cells # Meiosis does not produce exact copies, mitosis does # Crossing over occurs in meiosis # Mitosis produces diploid cells, meiosis produces haploid Similarities: # Both duplicate the organism's genome once, before any duplication occurs # Metaphase plates occur in both # Centrioles exist in both # They share the same basic steps for division # Both occur in eukaryotic cells
List the key difference between meiosis 1 and 2?
Meiosis I is reductional but meiosis II is equational division .
List one possible consequence of errors in mitosis or meiosis?
A possible consequence of errors during mitosis could be that two daughter cells don't contain the correct amount od chromosomes. This would result in the cell killing itself during interphase because of this genectic error.
List at least one type of organism that does not undergo meiosis?
Bacteria (prokaryotes) do not undergo meiosis. They reproduce through a process called binary fission, which is a form of asexual reproduction.
Mitosis results in the formation of how many cells?
Two identical daughters cells are produced from a single parent cell due to mitosis. i guess he answered it for ya xD

List the key differences between mitosis and meiosis?
Mitosis is the process in which a cell's nucleus replicates and divides. Mitosis results in two cells that are genetically identical. These cells are necessary for growth and replacement of worn out cells, as well as for asexual reproduction (reproduction without eggs and sperm) that takes place in some organisms. Meiosis is the process of cell division in which the cell's genetic information is randomly mixed and divided into sex cells, each having half the normal number of chromosomes. These cells can later combine to form offspring with the full number of chromosomes, but each new offspring will have a unique genetic inheritance.
What are the Compare and contrast signal words?
Google "signal words" and you will get a list. Comparing and contrasting means you are looking for similarities and differences between two things.

What is the method for comparing and contrasting?
To compare and contrast, identify similarities and differences between two or more subjects. Create a list or table to organize your findings. Analyze the information to draw conclusions about how the subjects are alike and how they are different.

How would you compare yourself to something?
Comparing means finding things that are similar and different. Make a list for whatever it is you're comparing yourself to. How are you similar to that thing and how are you different?
Who introduce selection sorting algorithm?
in selection sorting at first we take first element of the list and start comparing with all the successive element of that list
