Scaling of double and single stranded DNA

Long double stranded DNA (DsDNA) and single stranded DNA (ssDNA) molecules were studied by direct imaging with the Atomic Force Microscope (AFM) in order to determine their scaling properties, exponents, distributions and persistence length in the frame work of the theory of polymer physics and at the single molecule level. The effects of the topology on the statistical properties were investigated by considering linear, circular and knotted DNA molecules
