We explored the two mechanisms of unistep hole transfer and multistep hole transport in DNA and in model finite systems, establishing the energetic control of the mechanism of charge migration in DNA.
It is possible to obtain a sample of crystalline glucose in which all the molecules have the α structure or all have the β structure. The α form melts at 146°C and has a specific rotation of +112°, while the β form melts at 150°C and has a specific rotation of +18.7°.
1 sty 2016 · Our laboratory has focused on studies of DNA charge transport (CT), wherein charges can efficiently travel long molecular distances through the DNA helix while maintaining an exquisite sensitivity to base pair π-stacking.
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
Here, we summarize the main unique properties of α-nucleosides, for example, their higher stability compared to the β-anomer, specific parallel double-stranded structure of α-β duplex, inhibition of tumors, bacteria and malaria parasites, and other biological properties.
17 sie 2020 · Here we report charge-transport measurements through single 30-nm-long double-stranded DNA (dsDNA) molecules with an experimental set-up that enables us to address individual molecules...
16 lis 2023 · The beta anomer was requested, so the OH on the anomeric carbon (C1) is cis to C6. Since C6 is top face (pointing up), the OH will be top face. Carbons 2, 3, and 4 are then arranged based on the Fischer projection arrangement at those carbons (C2 right, C3 left, and C4 left).
