What is the role of NaCl and EDTA in DNA isolation?

1 answer:

4 0

<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>

You need to use the equation PV = nRT

The only “trick” in these problems is you need to use the correct UNITS. Especially for the “R” value.

If you get the units (eg temps in Celsius or Kelvin) corresponding to the correct “matching” units of the other variables.

You need to convert the temp into Kelvin first
