Что (кто) такое metaphase spindle - определение

ARRAY OF MICROTUBULES AND ASSOCIATED MOLECULES THAT FORMS BETWEEN OPPOSITE POLES OF A EUKARYOTIC CELL DURING MITOSIS OR MEIOSIS AND SERVES TO MOVE THE DUPLICATED CHROMOSOMES APART
Spindle fiber; Mitotic apparatus; Nuclear spindle; Mitotic spindles; Metaphase plate; Spindle fibers; Mitotic spindle apparatus; Meiotic spindle; Spindle pole; Mitotic spindle; The spindle apparatus; The Spindle apparatus; Spindle (cell); Anastral microtubules; Spindle poles; Karyokinetic spindle
  • [[Micrograph]] showing condensed [[chromosome]]s in [[blue]], [[kinetochore]]s in [[pink]], and [[microtubule]]s in [[green]] during [[metaphase]] of [[mitosis]]
  • This diagram depicts the organization of a typical mitotic spindle found in animal cells. Chromosomes are attached to [[kinetochore]] [[microtubule]]s via a multiprotein complex called the kinetochore. Polar microtubules interdigitate at the spindle midzone and push the spindle poles apart via [[motor protein]]s. [[Astral microtubules]] anchor the spindle poles to the [[cell membrane]]. Microtubule polymerization is nucleated at the [[microtubule organizing center]].
  • In the centrosome-mediated "search and capture" model (left), microtubules nucleated from centrosomes contact chromosomes by chance and become stabilized at kinetochores to form the spindle. In the chromatin-mediated "self-organization" model (right), microtubules are nucleated around the vicinity of mitotic chromatin and organized into a bipolar array by motor proteins.
  • Cartoon of the dividing epithelium cell surrounded by epithelium tissue. Spindle apparatus rotates inside the cell. The rotation is a result of astral microtubules pulling towards tri-cellular-junctions (TCJ), signaling centers localized at the regions where three cells meet.

Spindle apparatus         
In cell biology, the spindle apparatus refers to the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis, a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis, a process that produces gametes with half the number of chromosomes of the parent cell.

Spindle (disk packaging)
In the context of computer supplies, the word spindle or cakebox may refer to a plastic container for packaging optical discs. It typically consists of a round base with a vertical rod (which matches the center holes of the disks) and a cylindrical cover made from polypropylene plastic.

Wharve; Spindle-whorl; Spindle whorls
A spindle whorl is a disc or spherical object fitted onto the spindle to increase and maintain the speed of the spin. Historically, whorls have been made of materials like amber, antler, bone, ceramic, coral, glass, stone, metal (iron, lead, lead alloy), and wood (oak).

ROTATING AXIS OF A MACHINE TOOL
Spindle (woodworking tool); High speed spindle; High-speed spindle
In machine tools, a spindle is a rotating axis of the machine, which often has a shaft at its heart. The shaft itself is called a spindle, but also, in shop-floor practice, the word often is used metonymically to refer to the entire rotary unit, including not only the shaft itself, but its bearings and anything attached to it (chuck, etc.

Spindle apparatus

In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis, a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis, a process that produces gametes with half the number of chromosomes of the parent cell.

Besides chromosomes, the spindle apparatus is composed of hundreds of proteins. Microtubules comprise the most abundant components of the machinery.
