Checkpoints are control mechanisms that ensure the proper timing of cell cycle events by enforcing the dependency of late events on the completion of early events (Hartwell and Weinert, 1989). Entry ...

Cell cycle controls ensure that DNA replication (S phase) follows mitosis resulting in two precise copies of the genome. A failure of the control mechanisms can result in multiple rounds of DNA ...

Tsukuba, Japan - Cell division of a mother cell to produce two identical daughter cells is known as mitosis. This underlies the early embryonic development of sea squirts, when it changes from being ...

In textbooks, the grand-finale of cell division is the tug-of-war fought inside dividing cells as duplicated pairs of chromosomes get dragged in opposite directions into daughter cells. This process, ...

The synchronous mitosis of early embryonic development switches to a patterned form at the 11th cell division following removal of a cell cycle compensatory mechanism, new research shows. An ...
