There are three phase transitions in a cell cycle: G1/S to initiate DNA synthesis, G2/M to enter mitosis, and metaphase/anaphase to exit mitosis. Different models of cell cycle regulation ...

The primary G1/S cell cycle checkpoint regulates eukaryotic cells’ commitment to enter DNA synthesis (S phase) and serves as a stop/go decision prior to cell division. Cyclin-dependent kinase ...

This free eBook from Cell Signaling Technology explores the cell cycle and DNA damage and repair.

"If there is a problem with DNA packaging, the cell quickly senses this issue. But instead of triggering a typical stress response, the cell responds by slowing down its cycle of growth and division, ...

Enzo Life Sciences Nuclear-ID ™ Red DNA stain is useful for staging cells on the basis of their DNA content. The stain can be applied to live, detergent-permeabilized or fixed cells for ...

Schauer said the team used flow cytometry to study the DNA content and processes of cells ... Shaw et al, Revised mechanism of hydroxyurea-induced cell cycle arrest and an improved alternative ...

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 ...

It starts with circular snippets of DNA called plasmids. The DNA is made in large vats of an amber-colored solution containing specially designed E. coli bacteria. When completed, the solution ...

His special expertise is on a very important group of proteins called histones that are used to package DNA in all organisms ... stages of their cell division cycle to answer questions about ...
