Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment has been the focus of a 30-year research question. New work from the Crick ...

A new study has uncovered a hidden step that helps the deadliest malaria parasite survive and multiply inside the human body. Researchers studying Plasmodium falciparum found that the parasite relies ...

DNA replication in viral systems encompasses a remarkable variety of strategies that exploit or mimic cellular machinery. Small DNA viruses often encode a multifunctional helicase–primase complex that ...

THE precursor of life may have learned how to copy itself thanks to simple convection at the bottom of the ocean. Lab experiments reveal how DNA replication could have occurred in tiny pores around ...

Definition: A microarray is a small, flat substrate carrying an ordered grid of microscopic probe features, each containing a known biological molecule, that is used to measure many molecular targets ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...
