Scientists have long theorized that the way in which the roughly three meters of DNA in a human cell is packaged to fit within a nuclear space just six microns wide, affects gene expression. Now, Whitehead Institute researchers present the first evidence that DNA structure does indeed have such effects--in this case finding a link between chromosome structure and the expression and repression of key genes.
