...nown as 53BP1, recognizes a molecular site usually hidden within the DNA-packaging structure called chromatin, which makes up our chromosomes. Chromatin consists of DNA coiled around the edges of molecules called histones to form disk-shaped entities called nucleosomes. The nucleosomes themselves, then, are...

And while that discovery is novel enough to please any scientist, it's the implication that those perfectly preserved plants may suggest that really excites him.
