Abstract
MANY natural and synthetic high polymer solutions have lower friction in turbulent flow than the pure solvent1. In an effort to devise an experiment to explain the mechanism involved, flow studies were made using deoxyribonucleic acid (DNA) together with various carcinogens, steroids, acridine dyes, an antibiotic, and other materials which modify the effective molecular size, shape, and weight of the dissolved DNA. While the mechanism of friction reduction is still as elusive after these experiments as before, the interesting differences in turbulent flow properties of the various DNA-additive complexes may point to a simple way of estimating the effects of additives on the configuration of the DNA molecule.
