(1 of 4) Photomicrograph of a cell dividing: nucleus is visible as dark staining organelle.
(2 of 4) Cell dividing: chromosomes are visible and lined up at the plane of division.
(3 of 4) Cell dividing: chromosomes are being pulled toward the cellular poles.
An electron micrograph of a mouse liver cell. Magnification approximately 12,000 times.
DNAFTB Animation 7: Walther Flemming explains the phases of mitosis.
Virus particle budding out from the cell. Although similar to the previous micrograph, the inner core is not as dense and therefore this is an "immature" viron budding out as opposed to a mature virus fusing in to infect a cell.
In 1882, Walther Flemming published the definitive study of the cellular process of mitosis.
"Italians (mother and daughter)"
Bruce Stillman, Ph.D., president of Cold Spring Harbor Laboratory, explains that genomic instability is a characteristic of cancer cells.
