(met´ a phase) [Gr. meta: between] • The stage in nuclear division at which the centromeres of the highly supercoiled chromosomes are all lying on a plane (the metaphase plane or plate) perpendicular to a line connecting the division poles.
stage of mitosis in which chromatids are lined up along an imaginary line (equator) at the center of what had been the nucleus and spindle fibers radiating from each centriole are attaching to the centromeres.
one of the 5 mitosis phases (prophase, prometaphase, metaphase, anaphase, and telophase). Originally based on light microscopy of living cells and electron microscopy of fixed and stained cells. At metaphase kinetochore microtubules align chromosomes in one midpoint plane. Metaphase ends when sister kinetochores separate. (More? Week 1 Notes | Week 1 Mitosis)
(MEH-tah-faze) the second stage of mitosis in which the chromosomes are aligned along the center of the dividing cell.
the stage during mitosis in which the pairs of chromatids line up on the equatorial plate.
The stage of mitosis in which the chromosomes line up along the equatorial plane of the cell.
A stage in cell division when chromosomes align along the metaphase plate in the center of the cell.
A stage of cell division, in which the chromosomes are compact, and lined up along the centre of the cell. Metaphase chromosomes can be seen easily under a microscope, and so are suitable for cytogenetic analysis.
The stage in mitosis during which the chromosomes are aligned along a single plane in the centre of the cell. This stage is the briefest stage of mitosis. Each chromosome can clearly be observed as a pair of joined identical chromatids. The stage ends as soon as the centromeres connecting the pairs to each other break. Microtubules: Thin tubules made up of proteins that are used to make up structures involved in cellular movement.
A stage of nuclear division in eukaryote cells, occurring once in mitosis and twice in meiosis. This phase begins when all of the centromeres line up at the equatorial plane.
Phase of mitosis, or cell division, when the chromosomes align along the center of the cell. Because metaphase chromosomes are highly condensed, scientists use these chromosomes for gene mapping and identifying chromosomal aberrations.
Gk. meta, middle + phasis, form] The second stage of mitosis. During metaphase, all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle.
The stage in mitosis and meiosis during which chromosomes align along the equatorial plane of the cell.
The stage of eukaryotic cell division ( mitosis or meiosis) in which the chromosomes line up at the equator of the cell. PICTURE
phase of mitosis in which the chromosome pairs line up at the equator of the cell
the second stage of mitosis during which the chromatid pairs align at the cell’s equator.
(MET-uh-faze) The third phase of cell division, following prometaphase and preceding anaphase. In metaphase, the copied chromosomes align in the middle of the spindle.
Mitotic stage at which chromosomes are fully condensed and attached to the mitotic spindle at its equator but have not yet started to segregate toward the opposite spindle poles.
The stage of cell division in which the condensed chromosomes lie in a central plane between the two poles of the cell, and in which the chromosomes become attached to the spindle fibers.
The stage during cell division in which the chromosomes are arranged in an equatorial plate.
An intermediate stage of nuclear division when chromosomes align along the equatorial plane of the cell.
metafase] the stage in mitosis or meiosis when the chromosomes gather at the equator of the spindle and become aligned.
A stage in mitosis or meiosis during which the chromosomes are aligned along the equatorial plane of the cell.
stage of mitosis in which replicated chromosomes align at the center of the cell.
the phase of mitosis in which the chromosomes line up at the equator (the central plane) of the cell.
The third stage (of four stages) of mitosis (or meiosis), at which the chromosomes, attached in a plate-like formation to a structure in the cell called a spindle, are easily distinguished with a microscope, and can be photographed to construct a karyotype.
One of the phases of mitosis; where individual divalent sister chromatids are separated (metaphase) and drawn to each end of the cell (anaphase).
Metaphase, from the ancient Greek μετα (after) and φασις (stage), is a stage of mitosis in the eukaryotic cell cycle in which condensed chromosomes, carrying genetic information, align in the middle of the cell before being separated into each of the two daughter cells.
