New model for reproduction of E. coli bacteria

With a new model, AMOLF researchers reveal how single-celled organisms like bacteria coordinate growth, cell division and DNA replication. Bacteria reproduce via growth and cell division. During each cycle of growth and division, ...

Replication protein A and WAS protein partner to fix damaged DNA

An article published in the journal Frontiers in Cellular and Infection Microbiology reports a study by researchers at the State University of Campinas (UNICAMP) and the University of São Paulo (USP) in Brazil showing how ...

A step on the way to better therapies against viruses

Most cells can defend themselves against viruses after they have been activated by the body's own messenger substances (interferons). This happens with the help of proteins that recognize invading virus components and interfere ...
