The Domino and Clock Models of Cell Cycle Regulation Different models of cell cycle regulation converged when scientists realized that different model organisms shared the same molecules.

When looking at cells with a microscope, the length of different stages of the cell cycle can be estimated using the formula: \(\text{Length of time in phase}=\) \(\frac{\text{observed number of ...

The ability to identify cell cycle position through DNA content analysis ... on an Axio Observer Z1 wide-field fluorescence microscope equipped with an Apotome slider module (Zeiss).

Confocal images were acquired by using an Evident FV1000 confocal microscope. (Red: cell cycle G1 phase, Green: cell cycle S/G2/M phase) Image data courtesy of: Asako Sakaue-Sawano, Ph.D. Atsushi ...
