abstract:In biochemistry and molecular genetics, an AP site (apurinic/apyrimidinic site), also known as an abasic site, is a location in DNA that has neither a purine nor a pyrimidine base, either spontaneously or due to DNA damage. It has been estimated that under physiological condition 10,000 apurinic sites may be generated in a cell daily.
On Wednesday the AP printed a story based on a fake press release sent from a site designed to mirror the look and feel of a real corporate newsroom, even down to the logo.
