ScienceDaily (Mar. 5, 2010) In the long evolutionary road from bacteria to humans, a major milestone occurred some 1.5 billion years ago when microbes started building closets for all their stuff, storing DNA inside a nucleus, for example, or cramming all the energy machinery inside mitochondria.

Scientists have now sequenced the genome of a weird, single-celled organism called Naegleria gruberi that is telling biologists about that transition from prokaryotes, which function just fine with all their proteins floating around in a soup, to eukaryotes, which neatly compartmentalize those proteins?

More than 50 years have passed since Watson and Crick untangled the structure of DNA and five years have elapsed since scientists finished sequencing the entire human genome. What have we figured out about our genetic material?
