The story of life’s beginnings gets stranger when you look closely at viruses. These tiny entities seem to sit at the edge of biology.

A giant DNA virus pulled from a Japanese freshwater pond is forcing scientists to rethink how complex cells first acquired their defining feature: the nucleus. Named ushikuvirus, the newly ...

Researchers simulated nearly every molecule in a bacterial cell — and then watched the cell grow and reproduce.

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Researchers in Japan have identified a striking new way immune cells strip DNA out of dying neighbors, a process they call ...

Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic ...

A fleeting DNA fold called i‑DNA can switch cancer‑related genes on and off, revealing a hidden structural weak point that ...

By simulating the life cycle of a minimal bacterial cell—from DNA replication to protein translation to metabolism and cell ...

Cells were long believed to safeguard nuclear contents, releasing them only during cell death. Extracellular DNA was thought ...

More than 200 metabolic enzymes, many of which are normally tasked with producing energy in the mitochondria, are also found sitting directly on top of human DNA, according to a study published in ...

Scientists have recently been learning more about the importance of small bits of circular genetic material known as extrachromosomal DNA (ecDNA). These little circles of DNA can hitch a ride with ...
