Study reveals how protein machinery binds and wraps DNA to start replication
(PhysOrg.com) -- Before any cell - healthy or cancerous - can divide, it has to replicate its DNA. So scientists who want to know how normal cells work - and perhaps how to stop abnormal ones - are keen to ...

Newly discovered mechanism in cell division has implications for chromosome's role in cancer
"A biologist, a physicist, and a nanotechnologist walk into a..." sounds like the start of a joke. Instead, it was the start of a collaboration that has helped to decipher a critical, but so far largely unstudied, ...
