Question

what is the charge on human DNA
​

Answer 1

Explanation:

DNA is negatively charged, due to the phosphate groups in its phosphate-sugar backbone, so histones bind with DNA very tightly.

Answer 2

Explain why DNA has an overall negative charge. Phosphate groups in the DNA backbone carry negatively-charged oxygen molecules giving the phosphate-sugar backbone of DNA an overall negative charge. ... The negatively charged DNA can be pulled toward the positive field of the gel.
