In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...
In testing the genetic material of current populations in Africa and comparing against existing fossil evidence of early Homo sapiens populations there, researchers have uncovered a new model of human ...
An illustration of DNA broken into two pieces. A decade after CRISPR started to become a major tool in genetic research, a new generation of scientists is growing up with the technology. Even high ...
