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

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

New research suggests DNA may not need activation, challenging a long-held idea about how life began and reshaping ...

DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated-able to read not only the ...

Scientists from Skoltech and the University of Potsdam have developed a physical theory that sheds light on how molecular ...

Working on human pus in a medieval castle, Miescher discovered a substance that would eventually unlock our understanding of ...

A team has unearthed new findings about what happens during the minutes and hours after a cell divides, expanding our understanding of human biology -- and potentially leading to better medicines. DNA ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...
