What is Anaphase (anaphase)
Definition:
Anaphase is
the stage of the process of mitosis and meiosis where the chromosomes begin to
move to the opposite end (pole) of the separating cell.
In the cell cycle, the
cell prepares for division with increasing size, so it can produce more
organelles and can synthesize DNA. In mitosis, DNA is divided equally among the
two daughter cells. In the meiotic process the DNA of the four haploid cells.
Cell division requires a lot of movement inside the cell.
Chromosomes are moved
by spindle fibers to ensure that each cell has the correct number of
chromosomes after splitting.
Mitosis
Anaphase is the third
of four mitotic phases. The four phases are: Prophase, Metaphase, Anaphase, and
Telophase. In the prophase, the chromosomes migrate to the center of the cell.
In metaphase, the chromosome is in the middle (equator) of the cell. In
anafase, the paired paired chromosomes, known as twin chromatids, separate and
begin to move to the opposite poles of the cell. In telofases, chromosomes are
separated into new nuclei as cells divide, dividing the contents between two
cells.
Meiosis
In meiosis, four
tillers are produced, each having a chromosome material with half the number of
chromosomes as the original cell. The genital cells are produced by this cell
division. Meiosis consists of two stages: Meiosis I and Meiosis II. The
dividing cell passes through two phases of prophase, metaphase, anaphase, and
telophase.
In anaphase I, twin
chromatids begin to move to opposite poles of cells. Unlike mitosis, twin
chromatids are not separate. At the end of meiosis I, two cells are formed with
half the number of chromosomes as the original cell. Each chromosome contains
two chromatids instead of a single chromatid.
In meiosis II, the two
cells divide again. In anaphase II, the twin chromatids are separated. Each
separate chromosome consists of a single chromatid and is considered a full
chromosome. At the end of meiosis II, four haploid cells are produced.
