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 ...

Study reveals new role for RNA interference during chromosomal replication

At the same time that a cell's DNA gets duplicated, a third of it gets super-compacted into repetitive clumps called heterochromatin. This dense packing serves to repress or "silence" the DNA sequences within -- which could ...

Self-replication

Self-replication is any process by which a thing might make a copy of itself. Biological cells, given suitable environments, reproduce by cell division. During cell division, DNA is replicated and can be transmitted to offspring during reproduction. Biological viruses can reproduce, but only by commandeering the reproductive machinery of cells through a process of infection. Computer viruses reproduce using the hardware and software already present on computers.
