Our DNA is constantly being packed and unpacked. And there is a good reason for this: depending on its packing state, it performs different functions in the cell nucleus. For most of its life – this ...

A prevailing belief that the 3D structure of DNA disappears completely when cells divide has been overturned. Rather than DNA fully unwinding into a flat configuration, some regions of chromosomes ...

A research team led by UAB researcher David Reverter has discovered the molecular mechanism that describes in detail 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 ...

(Nanowerk News) 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 ...

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.

Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...

Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal metabolic processes or external stressors such as radiation or chemical ...
