Abstract
At low salt and high [calf thymus or chicken blood] DNA concentration, rodlike DNA molecules form specific aggregates containing about 7 parallel DNA molecules packed in a bundle. Bundle formation can be reversed by addition of small amounts of EDTA, and formation of the specific aggregates can be induced at higher salt concentration by addition of trivalent ions. In contrast to monomeric DNA, the aggregated species has the optical anisotropy expected for the B form as observed in fibers.Keywords
