Genetic Architects Untwist DNA’s Turns With Crispr

When scientists finished sequencing the human genome in 2003, many researchers focused their attention on decoding the long strings of As, Ts, Gs and Cs as the way to understanding the mysteries of human genetics. The genome, however, doesn’t appear in nature as a simple long line of letters. Unfurled, the genome stretches for nearly two meters, yet it folds itself in coils and loops to fit inside a nucleus less than 10 microns in diameter.
