Every cell in the body has the same DNA, but different cell types—such as muscle or brain cells—use different parts of it.

Michael Buck, PhD, professor of biochemistry in the Jacobs School, recently received NIH funding to explore how molecular readers of DNA access and activate seemingly hidden genes.

Long dismissed as evolutionary leftovers, segments of DNA once labeled “junk” may now offer a novel way to kill off deadly ...

The RAD52-DNA complex is a dynamic guardian of genomic stability. When this balance falters, cells may either self-destruct or, worse, turn cancerous.

New research from the University of Wisconsin–Madison reveals that dysfunction in a protein essential to maintaining ...

The 55th Lewis S. Rosenstiel Award for Distinguished Work in Basic Medical Research has been awarded to professor Steven ...

DNA replication is a semi-conservative process in which half of the newly synthesized strands (daughters) are derived from the original strands (mothers). The confirmation of semi-conservative ...

DNA stands for Deoxyribonucleic Acid, the molecule that carries the genetic code of all living things. It’s found in every cell and determines everything from your looks to your body functions. In ...

For more than 40 years, the person responsible for the brutal rape and murder of a 16-year-old girl on Long Island has eluded capture. DNA from a smoothie straw, prosecutors say, could now be the key ...
