Does mitosis occur in eukaryotic cells?
Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell.
Where does mitosis usually occur?
Mitosis occurs in every cell of the body except in germ cells which are produced from meiotic cell division.
Where does mitosis occur in prokaryotes?
Mitotic Spindle Apparatus
|Table 1. Mitotic Spindle Evolution|
|Structure of genetic material|
|Prokaryotes||There is no nucleus. The single, circular chromosome exists in a region of cytoplasm called the nucleoid.|
|Some protists||Linear chromosomes exist in the nucleus.|
|Other protists||Linear chromosomes exist in the nucleus.|
Where does meiosis occur?
Meiosis is the process of cells splitting into four haploid cells, thus reducing the chromosome number by half in each cell. They also give rise to gametes in the human body, but plant spores in plants. Meiosis occurs in the sex cells, so the sperm and egg cells in the human body, to create even more of themselves.
Does mitotic cell division occur in prokaryotes?
Prokaryotes, such as bacteria, do not have a nuclear membrane surrounding their cellular DNA, so cell division is happens differently than in eukaryotes. Even though the cell does not undergo mitosis, the end result is the same.
Does either mitosis or meiosis happen in prokaryotes?
No, prokaryotes do not undergo mitosis or meiosis. Prokaryotic cells divide by binary fission. It is similar to mitosis, which requires replication of DNA and then equal division of genetic material and cytoplasm, to form two daughter cells.
