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 ...

The cell cycle has been the subject of intense investigation during two periods since Virchow's 1855 realization that cells only arise from pre-existing cells. At the turn of the century ...

A new study from Cornell University has strengthened the case for using a specific group of molecules—known as microRNAs—as ...

Cornell researchers have confirmed that a previously identified biomarker for detecting the presence of malignant testicular ...

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 ...

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

28 If the ovum does not join with a sperm cell in the oviduct, the lining of the uterus begins to break down again and the cycle repeats. Figure caption, The thickness of the uterus lining varies ...

Cornell researchers have confirmed that a previously identified biomarker for detecting the presence of malignant testicular germ cell tumors has the potential to improve patient outcomes through ...
