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 ...

Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

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 ...

An artificial cell assembled from non-living chemical components has been created that can take in nutrients, grow, divide ...

Tiny, quivering spheres designed to feed and multiply raise prospect of artificial organisms to make drugs, food and fuel ...

Despite its utility, PCR’s main limitation is that it requires precise cycles of heating and cooling to amplify DNA. The thermal cyclers that perform this operation are clunky, relatively expensive, ...

As genome editing therapies move through clinical trials to regulatory approval, scientists continue the quest for the holy ...
