To accomplish this, the DNA becomes highly compacted into the classic metaphase chromosomes that can be seen with a light microscope. Once a cell has divided, its chromosomes uncoil again.

How would this process differ if the centrosomes were not on opposite poles of the cell? Metaphase: The hallmark of this phase is the metaphase plate, where all of the chromosomes are lined up in the ...

Each chromosome pair viewed in a karyotype appears ... After a period of cell growth and multiplication, dividing cells are arrested in metaphase by addition of colchicine, which poisons the ...

Prophase The DNA in chromosomes and their copies condenses to become more visible. The membrane around the nucleus disappears. Metaphase Chromosomes and their copies line up in the middle of the cell.

The chromosomes align along the metaphase plate. As in mitosis metaphase, (and unlike meiosis metaphase I), fibers from the centrioles begin to pull on each one of the chromosomes from both ...
