WebThe strength and properties of the backbone are due to the formation of phosphodiester bonds. The backbone is highly negative in charge, exhibits repulsive forces and is hydrophobic. Their negative charges are neutralized and stabilized by Histone proteins, and metal ions such as magnesium and polyamines. WebThe reason why DNA is negatively charged is the phosphate group that makes up every nucleotide (pentose + nitrogenous base + phosphate). When forming part of the phosphodiester bond, they retain 1 of 2 negative charges (the other being lost to form the other ester bond to a new pentose, that's why the bond is called "phospho-di-ester"). simple linear regression model using python
