Ultraviolet light irradiation of PM2 superhelical DNA.
Superhelical PM2 DNA can be photochemically modified by u.v. irradiation. The variation of S20,w with dose shows the following characteristics. There is a linear increase from 28 to 31s produced by a low dose of u.v. irradiation (4,000 ergs/mm2). A plateau in S20,w occurs between 4,000 and 10,000 er...
