A cell during anaphase. Microtubules are visible in green. Stages of late M phase in a vertebrate cell. Anaphase (from Ancient Greek ἀνα-() 'back, backward' and φάσις (phásis) 'appearance') is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell.
In cell biology, the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell division. The same proteins responsible for muscle contraction, actin and myosin, begin the process of ...
Anaphase lag is a consequence of an event during cell division where sister chromatids do not properly separate from each other because of improper spindle formation. [1] The chromosome or chromatid does not properly migrate during anaphase and the daughter cells will lose some genetic information. It is one of many causes of aneuploidy.
Cohesin is a multi-subunit protein complex, made up of SMC1, SMC3, RAD21 and SCC3 (SA1 or SA2). [ 3 ] SMC1 and SMC3 are members of the Structural Maintenance of Chromosomes (SMC) family. SMC proteins have two main structural characteristics: an ATP-binding cassette -like 'head' domain with ATPase activity (formed by the interaction of the N ...
Ciliate undergoing cytokinesis, with the cleavage furrow being clearly visible. Cytokinesis (/ ˌsaɪtoʊkɪˈniːsɪs /) is the part of the cell division process and part of mitosis during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear ...
Mitotic checkpoint serine/threonine-protein kinase BUB1 also known as BUB1 (budding uninhibited by benzimidazoles 1) is an enzyme that in humans is encoded by the BUB1 gene. [ 5 ] [ 6 ] Bub1 is a serine/threonine protein kinase first identified in genetic screens of Saccharomyces cerevisiae . [ 7 ]
The Russian Wikipedia (Russian: Русская Википедия, romanized:Russkaya Vikipediya) is the Russian-language edition of Wikipedia. As of October 2024, it has 2,003,653 articles. It was started on 11 May 2001. [ 1 ] In October 2015, it became the sixth-largest Wikipedia by the number of articles.
Microtubule polymerization is nucleated at the microtubule organizing center. An aster is a cellular structure shaped like a star, consisting of a centrosome and its associated microtubules during the early stages of mitosis in an animal cell. [ 1 ]: 221 Asters do not form during mitosis in plants. Astral rays, composed of microtubules, radiate ...
