Answer:
D: Nonpolar covalent bonds involve two atoms that have equal electonegativity whereas polar covalent bonds involve two atoms that are unequal in their electronegativity.
Explanation:
DNA is a negatively-charged molecule. Also cell membranes are negatively charged. The problem would be how to push this charges together? I<span>f you put some CaCl2 into the mixture, the CaCl2 will "split" giving 2Cl- and Ca2+. This last ion will be attracted by the negatively charged DNA and will "cover" it, hiding its negative charge. Hope this answers the question.</span>
