Metaphase

Metaphase is the stage of mitosis in which the chromosomes are located in the equatorial plane of the cell and consist of two chromatids, which are connected at one point - the centromere. In metaphase, each chromosome is presented in the form of a DNA double helix, which consists of two strands. This stage is one of the most important stages of mitosis, since it is at this moment that chromosomes separate and daughter cells with new genetic properties are formed.

Metaphase begins after the cell nucleus divides into two parts, each containing one chromosome. The chromosomes then begin to move towards the equator of the cell, where they are arranged in a lattice. Each chromosome consists of two chromatids - long strands of DNA that connect at one point - the centromere. In metaphase, centromeres are located at the equator of the cell, and chromatids are on opposite sides.

During metaphase, a number of important processes occur that prepare the cell for division. Firstly, chromosomes become visible thanks to special substances that are secreted in the cell. Secondly, the centromeres of chromosomes are strengthened by special proteins, which allows them to remain in place during cell division.

Metaphase is followed by prometaphase, when the chromatids begin to move apart in different directions of the cell. Anaphase then occurs, in which the chromatids separate into individual chromosomes. After anaphase comes telophase, which consists of compression of chromosomes in the nucleus and the formation of new nuclei in daughter cells.

Thus, metaphase is a very important stage of mitosis, which prepares the cell for division and creates new genetic properties in daughter cells.

Metaphases are the X from the metaphase stage of mitosis, which is those two chromatids connected at the same position by the centromere point. This is an important event in cytokinesis (cell division). During this process, the chromosomes are stretched and the centromeres are divided into two daughter cells, each of which receives its own copy of the genetic material.

During metaphase, the division of chromosomes into daughter cells begins using the so-called “Decomposition node”. This occurs due to the rotation of paired chromotides around each centromeric DNA molecule. The daughter chromotins gradually separate, each forming a separate daughter cell. Eventually, the two separated cells become completely separate from the central mother cell, which has completed mitosis. The end of metaphase is accompanied by bond fission, called apoptosis, which proceeds through the determination of the form of division of daughter cells. After the limp has drowned, the connection will become so
