PMAT may refer to: Plasma membrane monoamine transporter (PMAT) Four phases of mitosis: prophase, metaphase, anaphase, and telophase: Prophase: Chromatin into chromosomes, the nuclear envelope breaks down, chromosomes attach to spindle fibers by their centromeres. Metaphase: Chromosomes line up along the metaphase plate (center of the cell).
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
Cell division in prokaryotes (binary fission) and eukaryotes (mitosis and meiosis). The thick lines are chromosomes, and the thin blue lines are fibers pulling on the chromosomes and pushing the ends of the cell apart. The cell cycle in eukaryotes: I = Interphase, M = Mitosis, G 0 = Gap 0, G 1 = Gap 1, G 2 = Gap 2, S = Synthesis, G 3 = Gap 3.
Endopolyploidy occurs when in adult differentiated tissues the cells have ceased to divide by mitosis, but the nuclei contain more than the original somatic number of chromosomes. [44] In the endocycle ( endomitosis or endoreduplication ) chromosomes in a 'resting' nucleus undergo reduplication , the daughter chromosomes separating from each ...

In the 1930s, Stern demonstrated that genetic recombination, normal in meiosis, can also take place in mitosis. [ 7 ] [ 8 ] When it does, it results in somatic (body) mosaics. These organisms contain two or more genetically distinct types of tissue. [ 9 ]
