He settled on sperm donation as a way to allay the last of those concerns while helping other families have children. He never could have expected that, because of DNA testing, the day would come when he would be contacted by the children he helped create. Needless to say, neither could anyone else, including the sperm banks that historically promised anonymity to donors…

A New Tool To Sequence Circular DNA

University of Alberta biologists have invented a new way for sequencing circular DNA, according to a new study. The tool—called CIDER-Seq—will give other scientists rich, accurate data on circular DNA in any type of cell.
While our own DNA is linear, circular DNA is common in the genomes of bacteria and viruses. Scientists have also discovered circular DNA within the nuclei of human and plant cells, called extrachromosomal circular DNA (eccDNA). Recently, research has begun to investigate the role of eccDNA in human cancer—but progress has been hampered due to the lack of effective methods for studying and sequencing eccDNA.
