What are you trying to ask??????
<span>The following is the role of NaCl and EDTA in DNA isolation, hope it helps:
NaCl provides Na+ ions that will block negative charge from phosphates on DNA.
Negatively charged phosphates on DNA cause molecules to repel each other. The Na+ ions will form an ionic bond with the negatively charged phosphates on the DNA, neutralizing the negative charges and allowing the DNA molecules to come together.</span>
Transition metals will often violate the octet rule by using their d orbitals for bonding.
All I know us the San Andreas fault line. That earthquake is far overdo
We are covering the periodic table now in science. if I had to make a quick guess it would be that neurons are neutral so they Balance out the protons. it is just a guess so just warning. I hope this helped you in some way
