DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes.

(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 ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of ...

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 ...

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 ...

A time-delay circuit enables precise control over the division of synthetic DNA droplets, which mimic biological Liquid-Liquid Phase Separation (LLPS) droplets found in cells. By utilizing a ...

Researchers at the Centre for Genomic Regulation (CRG) reveal that metabolic enzymes known for their roles in energy production and nucleotide synthesis are taking on unexpected "second jobs" within ...

Discovery reshapes understanding of how tumor cells repair broken DNA, pointing toward more precise cancer therapies.

Many cellular functions in the human body are controlled by biological droplets called Liquid-Liquid Phase Separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside ...
