Faster still and faster

[摘要] A new generation of DNA sequencing machines, such as the Solexa 1G machine, are paving the way for novel epigenetic discoveries. The latest approach fishes out all the DNA associated with a given marker, such as one of the histone proteins used to package genes in chromosomes. Then, instead of comparing each piece of DNA with a library of previously isolated sequences, as used to be done, scientists simply sequence the whole lot.
