Another quick question about grammar...
"...two large single stranded DNA, which have a low viscosity" (would it be have or has????)
have because you said "two, etc."
Frankly, one strand or two strands and viscosity have nothing to do with each other. Viscosity is a macroscopic characteristic (ie , trillion trillion trillion trillion molecules), and a strand is microscopic (in ones or twos). So a single strand cannot have viscosity. I would rephrase what you want to say...as a single strand of DNA moves quickly? (low viscosity flows quickly, as viscosity is resistance to flow).
