Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...

A major advance in cell biology has revealed how our cells safeguard their genetic material during one of the most vulnerable moments in their life cycle. The study identifies a specific protein ...

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...

Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours - sometimes more than a day - in a ...

As we get older, chemical marks on our DNA slowly shift. Now, a study reveals this 'drift' in gut stem cells is fueled by ...

A new single-cell profiling technique has mapped pre-malignant gene mutations and their effects in solid tissues for the first time, in a study led by investigators at Weill Cornell Medicine and the ...
