WebIf the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death ^2 2. WebA metaphase stage of mitotic cell division is best to prepare and analyze karyotype. To understand why only the metaphase stage is best! We have to first know the hierarchy of chromosomes. The chromosome is a complex network of DNA and protein which facilitate DNA packaging in a cell. Usually, chromosomes in other cell division phase aren’t ...
