Higher water temperatures induce specific chemical tags at targeted locations on the DNA of embryonic zebrafish. These "epigenetic" changes can then reroute genetic pathways, so that the embryos change sex. This finding, ...

In almost every human cell, 2 meters of DNA has to fit within a nucleus that is just 8 millionths of a meter wide. Like wool around a spool, the extreme space challenge requires DNA to wrap around structural proteins called ...

There is a sense in which the information encoded in a gene sequence can be represented by two bits per base pair location. The reality, however, is that this is far from a complete description. Although many academically ...
