The risk of error tends to increase with the complexity of the structural repeating units and the size of the DNA crystal to be assembled. (sciencedaily.com)
It's a polymer made of repeated units of two different molecules linked together: a giant ring - shaped molecule called beta - cyclodextrin that's made from cornstarch, and a fluorine - rich molecule called decafluorobiphenyl, or DFB. (sciencenews.org)
Specifically, the researchers noted that the cell wall of strep is composed primarily of a single molecule known as the group A carbohydrate (or GAC) which, in turn, is built from repeating units of the bacterial sugar rhamnose and the human - like sugar N - acetylglucosamine (GlcNAc).
