WebThe helix has a distinct narrow minor groove near the center of the molecule at the AAAA region. This suggests that the internal stabilizing forces due to base stacking and hydrogen-bonding interactions are sufficient to overcome the loss of connectivity associated with the disruption of the covalent backbone of DNA.

WebWe argue that, in addition to its coding function, the ability of DNA, unlike RNA, to adopt a B-DNA structure confers advantages both for information accessibility and for packaging. The information encoded by DNA is both digital - the precise base specifying, for example, amino acid sequences - and analogue. WebMar 19, 2024 · As the phosphate groups of DNA are negatively charged, the DNA strand has a negatively charged backbone. Each phosphorus atom forms bonds with negatively charged Oxygen atoms which is responsible for this negative charge on the molecule. So, to conclude, we can say that DNA is a negatively charged molecule.
