which chemical entity of DNA deoxynucleotide is responsible

which chemical entity of DNA (deoxynucleotide) is responsible for developing this net charge of DNA

Solution

Answer:

DNA (deoxyribonucleic acid) is a polynucleotide chain and composed of nucleotide monomers. Nucleotides are made up of sugar, phosphate and base. The phosphate moiety is negatively charged which imparts an overall negative charge to the DNA molcule.
