1. Define a cell cycle. How is the cell cycle controlled or regulated? Why does the cell cycle need to be regulated? What might happen if the cell cycle is not well- regulated or not regulated at all?

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 ...

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 ...

Figure 1: Progression through the mammalian cell cycle. Figure 2: Retinoblastoma protein and cell-cycle progression. Recent experiments have implicated one specific E2F target, CDC6, as a ...

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 ...

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 ...

Proliferating animal cells maintain a stable size distribution over generations despite fluctuations in cell growth and division size. Previously, we showed that cell size control involves both cell ...
