Study shows how DNA finds its match

It's been more than 50 years since James Watson and Francis Crick showed that DNA is a double helix of two strands that complement each other. But how does a short piece of DNA find its match, out of the millions of 'letters' ...

CRISPR-based tool maps gene function in human cells

UC San Francisco scientists have used a high-throughput CRISPR-based technique to rapidly map the functions of nearly 500 genes in human cells, many of them never before studied in detail.

DNA 'molecular scissors' discovered

(PhysOrg.com) -- Scientists at the University of Dundee have discovered a protein that acts as a 'molecular scissors' to repair damaged DNA in our cells, a finding which could have major implications for cancer treatments.
