  Metaphase
The prometaphase provides a transition from prophase to metaphase.
In prometaphase the nuclear envelope, which surrounds the nucleus, breaks up.
In Metaphase the kinetochores that are responsible for moving the chromosomes jump begin to orientate the chromosomes.

  Metaphase   (Site not responding. Last check: )
In the metaphase, the chromosomes align in the middle of the cell.
Metaphase (from the Greek words μετά = after and φάσις = stage) is a stage of mitosis in the eukaryotic cell cycle in which condensed chromosomes align in the middle of the cell before being separated into each of the two daughter cells.
Metaphase is preceded by prophase and followed by anaphase.

 Genial Metaphase Arresting Solution
Metaphase Arresting Solution is a gentle alternative to commonly used colchicines/colcemid preparations and is less toxic to cells because the concentration of colchicine is reduced while the extra blocking activity of vinblastine sulphate.
Both colchicine and vinblastine sulphate inhibit the formation of mitotic spindles and are used to increase the percentage of metaphase cells for chromosome analysis.
Metaphase Arresting Solution is supplied as a powder and when reconstituted as specified on the package insert becomes a 100ml working solution.

This metaphase has been hybridized with a "painting" probe for chromosome 4 which causes the entire chromosome to fluoresce.
This metaphase from the same individual as the cell above has been hybridized with a probe for the terminal part of chromosome 4q.
This is an example of a metaphase cell that has been hybridized with the probe for Steroid Sulfatase Deficiency which is caused by a microdeletion on the X chromosome.

 BioMed Central | Full text | Characterization of sub-nuclear changes in Caenorhabditis elegansembryos exposed to brief, ...
To determine if embryos exposed to anoxia contain metaphase blastomeres in which the metaphase plate size is altered, we measured the length (diameter of the metaphase plate) and the width of the metaphase plate in blastomeres of embryos, at similar developmental stages, exposed to either normoxic or anoxic conditions.
The spindle checkpoint components monitor kinetochore-microtubule attachment and tension and act to delay the metaphase to anaphase transition until all chromatids are attached to microtubules, thus ensuring the proper segregation of chromosomes [26,27].
The metaphase plate is "disc shaped" thus, to determine the length of the metaphase plate, which is the diameter, the focal plane in which the diameter was largest was used for calculations.

 Chromosome, Metaphase - Talk Medical
Chromosome, metaphase: A chromosome in the stage of the cell cycle (the sequence of events in the life of a cell) when a chromosome is most condensed and easiest to distinguish and so to study.
Metaphase chromosomes are often chosen for karyotyping and for chromosome analysis because they are readily seen..
The term "metaphase " was introduced by Strasburger in 1884 to denote the stage in nuclear division after (in Greek: meta) the time when he mistakenly thought chromosomes had just divided into chromatids.

Since the chromosome is attached to two sets of fibers, pulling in opposite directions, the whole chromosome structure is tugged into the center of the cell, where all of the kinetochores of all the chromosomes line up.
The alignment of all the chromosomes in the center of the cell (the equatorial plane) is a very distinctive event in metaphase.
At the end of metaphase, all the kinetochores are lined up on the equatorial plane, facing in opposite directions, and attached to the opposite poles of the cell by means of spindle fibers.

 SparkNotes: Mitosis: Metaphase and Anaphase
At the end of prometaphase, the centrosomes have aligned at opposite ends, or poles of the cell and chromosomes are being moved toward the center of the cell.
Metaphase is marked by the alignment of chromosomes at the center of the cell, half way between each of the mitoic spindle poles.
Metaphase can occupy a large portion of the total time of mitosis because chromosome alignment at the center of the cell on the metaphase plate acts as a checkpoint for progression into the next phase, anaphase.

The 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.

 Mechanical basis of meiotic metaphase arrest
CONTROL of the metaphase to anaphase transition is a central component of cell-cycle regulation.
Thus, metaphase arrest defines an important checkpoint in the meiotic cell cycle1.
We conclude that metaphase arrest results from the balancing of kinetochore forces due to chiasmata.

We found that the larger the bivalent, the closer to the centre of the metaphase plate it was situated.
Bivalents of equal size were approximately equidistant from the centre of the metaphase plate and formed concentric circles around the largest bivalent.
In spermatogonial metaphase, chromosomes were tightly brought together, forming a dense compact disk, whereas during metaphase I of spermatocytes, all bivalents were clearly separated from each other, and the distance between adjacent bivalents varied from 0.4 to 1.5 µm.

The "metaphase typewriter" was part of a project carried out by members of the Consciousness Theory Group to build machines to communicate with disembodied spirits, including spirits of the dead, beings from other dimensions or dissociated fragments of living personalities.
Ordinary awareness is one of the biggest mysteries of our age: scientists are totally baffled by the fact that humans enjoy "inner experience" along with their behavior and are at a loss to explain the origin of this experience tho much progress has been made in explaining the behavior.
For the next step in metaphase research I have proposed building quantum-driven communicators that are more consciousness-friendly than radioactive sources--devices that are more similar in size, operation and energy to the (purportedly) quantum synapses in human nervous systems.
