Dna is a negatively-charged molecule

WebNucleotides (Nitrogenous base+Phosphate+Pentose) are negatively charged due to the phosphate group that is formed during the production of DNA. When a phosphodiester bond is formed, nucleotides maintain one of two negative charges, which charges the entire DNA molecule, while the other negative charge is lost, resulting in the development of ... WebJul 6, 2011 · The negative charge on the phosphate group is stabilized as the charge is distributed all over the molecule. As DNA is negatively charged, it gets attracted towards positive electrode or anode in electrophoresis. The oxygen atoms in the phosphate group are negatively charged.
