(PhysOrg.com) -- Gene duplications are arguably the driving force of organismal evolution – and if they survive, such duplicate genes will diverge in both regulatory and coding genomic regions. Coding divergences, in ...
Rigorous analysis of the structures of thousands of plant proteins by Tetsuya Sakurai and colleagues from the RIKEN Center for Sustainable Resource Science has led to the construction of a database that will help scientists ...

Small stretches of DNA in the human genome are known as "pseudogenes" because, while their sequences are nearly identical to those of various genes, they have long been thought to be non-coding "junk" DNA.
