The intricate division of labor within a "crown-shaped" protein complex, which viruses use to replicate their ribonucleic ...

The avian influenza virus needs to mutate to cross the species barrier and to infect and replicate within mammalian cells. Scientists have now deciphered the structure of the avian influenza virus's ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

Proteins are the molecular workhorses of cells. To understand their functions, scientists soon realized that they had to figure out proteins’ shapes. But solving a protein structure is a challenging ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...
