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

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

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 ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Movie 1: Movement of single nucleosomes in living human cells. The movie shows nucleosome fluctuations in euchromatin (left), where gene expression is active, and in heterochromatin (right), where ...

Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple loop at the cell’s center. A giant microbe called Thiovulum imperiosus has now ...

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