Figure 6. Difference between single-stranded and double-stranded DNA for depurination at pH 5.1, 60°C.

Figure 6

(a) Time courses of depurination of M13 ssDNA and dsDNA. (○) M13 dsDNA; (•) M13 ssDNA. (b) The rate constants (k) of several kinds of DNA including ssDNA (M13 ssDNA and N30) and dsDNA (M13 dsDNA, Salmon sperm DNA and Lambda DNA). T m analysis showed that M13 dsDNA kept duplex form below 70°C at pH 5.1.
