The two strands of DNA, although chemically equivalent, are replicated and repaired asymmetrically. Insights into the persistence of DNA damage show how strand-specific interactions shape the ...
A molecular illustration of the crowded interior and cell envelope of Escherichia coli. (David S. Goodsell, The Scripps Research Institute) To replicate information, life usually has fairly ...
Researchers have mapped 50,000 of DNA's mysterious "knots" in the human genome. The innovative study of DNA's hidden structures may open up new approaches for treatment and diagnosis of diseases, ...
Most biochemistry labs that study DNA isolate it within a water-based solution that allows scientists to manipulate DNA without interacting with other molecules. They also tend to use heat to separate ...
