WebThe cytosine photohydrate can deaminate to uracil photohydrate and both of these eventually dehydrate to their parent bases (Patrick and Rahn 1976; Boorstein et al. 1990). In double stranded DNA, the half-lives of cytosine hydrate and uracil hydrate are 25 h and 6 h respectively at 37°C (Boorstein et al. 1990). WebIt is concluded that, in the monohydrate, the water molecule, but not the cytosine itself, may rotate (at a frequency of ca. 30 kHz at 200 K), the activation energy of rotation being 17.8±2.8 kJ mol –1.
