The study of the cell cycle focuses on mechanisms that regulate the timing and frequency of DNA duplication and cell division. As a biological concept, the cell cycle is defined as the period ...

Cell cycle transitions in eukaryotes are driven by cyclin-dependent kinases (for example, Cdk1 and Cdk2), which are regulated by the availability of their cyclin partners (for example, CycA and ...

Harvest cells, want good single cell suspension Count cells Dispense aliquots of 1 million cells into labeled tubes Add 5 ml PBS and centrifuge for 5 min at 400 x g. Re-suspend cell pellet in 300 ul ...

DNA’s iconic double helix has long been the symbol of life’s blueprint. However, the human genome conceals far more ...

Before a cell can divide, it must grow and make copies of all the organelles such as mitochondria and ribosomes. The cell must also replicate the chromosomes in the nucleus, then it can divide by ...

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 ...

A life cycle is the series of stages something passes through during its lifetime. We also use the term for things that are not living, like cell phones. The life cycle for anything you buy includes ...

In tumoral cells, the modulation of the G1/S phases of cell cycle is destabilized by amplification and high expression of cyclin E (CCNE) or by mutation or loss of retinoblastoma 1 (RB1) gene. Cancer ...
