A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life reconstructions ever created. Using computer technology, scientists have ...

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

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 ...

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

A team of researchers at VCU Massey Comprehensive Cancer Center has identified a new pathway through which mutations in the tumor suppressor p53 gene—found very frequently in human tumors—hijack DNA ...

Maize serves as a vital model species for advancing our understanding of plant biology, yet many mysteries remain about the intricate processes ...

The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...
