Chemical Structure

Caption: This image shows the differences in chemical structure of the 5-methylcytosine (5mC) base (left) from the 5-hydroxymethylcytosine (5hmC) base in DNA against a background of DNA sequencing imagery. Researchers at the University of Chicago, the Ludwig Institute for Cancer Research at the University of California, San Diego, and Emory University Have presented the first genomic map of 5hmC at single-base resolution. DNA 5hmC modification plays key roles in processes fundamental to life.
