Abstract
AbstractFluorescence depolarization was used to measure the rate of renaturation of T2 DNA, which had been modified by chloroacetaldehyde. Rates were measured on DNA samples with 5–15% of the base pairs modified and were found to agree with rates determined by DNA absorbance kinetics at 260 nm. The renaturation rate of a modified T2 DNA was unchanged in the presence of a ninefold abundance of unlabeled calf thymus DNA.
