Protein production is the biotechnological process of generating a specific protein. It is typically achieved by the manipulation of gene expression in an organism such that it expresses large amounts of a recombinant gene .
Lymphocytes can enter mitosis when they are activated by mitogens or antigens. B cells specifically can divide when they encounter an antigen matching their immunoglobulin . T cells undergo mitosis when stimulated by mitogens to produce small lymphocytes that are then responsible for the production of lymphokines , which are substances that ...
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.
Functions during mitosis [ edit ] The major function of mitosis is to separate replicated sister chromatids , and this is accomplished in part during anaphase A when "kinetochore microtubules (or kMTs)" that link the sister chromatids to opposite spindle poles shorten by depolymerization, exerting forces on the chromatids that pull them to the ...
Condensins are large protein complexes that play a central role in chromosome assembly and segregation during mitosis and meiosis (Figure 1). [ 1 ] [ 2 ] Their subunits were originally identified as major components of mitotic chromosomes assembled in Xenopus egg extracts .
High-protein diets have long been popular for weight loss. More recently, plant-based diets have also gained attention for helping people to lose weight and providing other health benefits.
When G 2 is completed, the cell enters a relatively brief period of nuclear and cellular division, composed of mitosis and cytokinesis, respectively. After the successful completion of mitosis and cytokinesis, both resulting daughter cells re-enter G 1 of interphase. In the cell cycle, interphase is preceded by telophase and cytokinesis of the ...
