Metaphase - Wikipedia
Metaphase (from the Greek μετά, "adjacent" and φάσις, "stage") is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase). These chromosomes, carrying genetic information, align in the equator of the cell before being separated into each of the two daughter cells.
Metaphase | Define Metaphase at Dictionary.com
The stage of cell division in which the duplicated chromosomes become aligned along the center of the cell, called the equatorial plate or metaphase plate.Metaphase lasts up to an hour, and ends in mitosis and the second division of meiosis when separation of the paired chromosomal strands (called chromatids) begins.

Metaphase I - Stages of Meiosis - Online Biology Dictionary
Metaphase I. After prophase I, crossing-over is complete. The tetrads move to a plane — called the "metaphase plate" — halfway between the two poles of the cell. Next, the spindle fibers attach to the centromeres of each chromosome.Both kinetochores of each sister chromatid pair are turned toward the same pole. As a result, both kinetochores attach to spindle fibers from the same pole.
Metaphase | Definition of Metaphase by Merriam-Webster
Metaphase definition is - the stage of mitosis and meiosis in which the chromosomes become arranged in the equatorial plane of the spindle.
Metaphase II - Stages of Meiosis - Online Biology Dictionary
Metaphase II. Note: Meiosis II is very similar to mitosis. In metaphase II, the second stage of meiosis II, in each of the two daughter cells produced by the first meiotic division (which are known as secondary germ cells), the spindle again draws the chromosomes to the metaphase plate. This time, unlike metaphase I, the two kinetochores of each centromere bind to spindle fibers from opposite ...

Metaphase - Definition and Stages in Mitosis and Meiosis ...
Metaphase Definition. Metaphase is a stage in eukaryotic cell division in which the chromosomes align on the metaphase plate in the middle of the cell.The stages of prophase and prometaphase come before metaphase. In those stages of cell division, the chromosomes are condensed, the spindle fibers form, and the nuclear envelope is broken down. During metaphase and late prometaphase, the cell ...
Meiosis Metaphase 1 | Science Trends
Meiosis is how sex cells reproduce, dividing their chromosomes by half to create four haploid cells which are distinct from the original cells that birthed them. Meiosis has two different phases: meiosis one (meiosis I) and meiosis two (meiosis II).These phases are further divided into sub-phases, and metaphase one is a sub-phase of meiosis one.. During metaphase one, the tetrads of the cell ...
How does metaphase 1 differ from metaphase in mitosis?
In mitosis metaphase the mitotic spindel attaches to one side of a pair of chromosomes and seperates them so that one chromosome ends up on each side.In metaphase 1 of meiosis, the mitotic spindel ...
