A research team has identified a new mechanism that controls DNA’s ability to replicate—and thereby a cell’s ability to ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

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

DNA, though tightly packed in the nucleus, is constantly threatened by damage from metabolism and external stressors. One particularly severe form of DNA damage is the so-called DNA–protein crosslinks ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

If measured from beginning to end, the DNA in our cells is too long to fit into the cell’s nucleus, explaining why it must be constantly folded and packaged. When it is time for cell division, and the ...

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 ...

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that ...

One of the most abundant living organisms on Earth may also be one of the most vulnerable. A group of ocean bacteria known as ...

A new study finds that a trait helping a marine bacterium survive and flourish today may ultimately become its Achilles Heel as ocean conditions continue to shift.
