The amount of information in a DNA sample is extraordinary, with a peek at over 4,000 types of genetic conditions and diseases. DNA specimens have helped police crack many tough cases, leading to ...

They swab the cheeks of strangers and pluck hairs from corpses. They travel hundreds of miles to entice their suspects with an old photograph, or sometimes a free drink. Cooperation is preferred, but ...

Scientists have created an unprecedented 3-dimensional structural model of a key molecular 'machine' known as the BAF complex, which modifies DNA architecture and is frequently mutated in cancer and ...

DNA contains foundational information needed to sustain life. Understanding how this information is stored and organized has been one of the greatest scientific challenges of the last century. With ...

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 ...
