The first crystal structure of an alternative DNA shape from the insulin gene has been revealed. The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a ...

Rosalind Franklin’s role in the discovery of the structure of DNA may have been different than previously believed. Franklin wasn’t the victim of data theft at the hands of James Watson and Francis ...

Scientists have created a new technique that can assess how mutations in the genome influence the packaging of DNA in cells. The genome is massive, and has to be carefully wrapped around proteins so ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...
