What is the cause of the overall negative charge of a molecule of DNA?
A) hydrogen bonding between base pairs
B) the phosphate backbone
C) the sugars
D) the antiparallel orientation of the DNA

Question

Quizplus · Accepted Answer

The overall negative charge of DNA is due to the presence of the phosphate groups in the backbone of the DNA molecule. These phosphate groups contain negatively charged oxygen atoms, which contribute to the overall negative charge of the DNA molecule. The hydrogen bonding between base pairs, the sugars, and the antiparallel orientation do not directly contribute to the negative charge of the molecule.
