These are X-shaped chromosomes with the centromere in the middle so that the two arms of the chromosomes are almost equal. A chromosome is metacentric if its two arms are roughly equal in length. In a normal human karyotype five chromosomes are considered metacentric: chromosomes 1 3 16 19 and 20 .
Anaphase (from the Greek ἀνά “up” and φάσις “stage”) is the stage of mitosis after the process of metaphase when replicated chromosomes are split and the newly-copied chromosomes ( daughter chromatids) are moved to opposite poles of the cell . Chromosomes also reach their overall maximum condensation in late anaphase to help chromosome segregation and the re -formation of the nucleus.
The primary result of mitosis and cytokinesis is the transfer of a parent cell s genome into two daughter cells. The genome is composed of a number of chromosomes —complexes of tightly coiled DNA that contain genetic information vital for proper cell function. Because each resultant daughter cell should be genetically identical to the parent cell the parent cell must make a copy of each …

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.
