At times, a specific fragment of the molecules of DNA which are analyzed needs to be separated. One of the methods is digesting the gels simply. Which of the following statement is not correct in with respect to it?

At times, a specific fragment of the molecules of DNA which are analyzed needs to be separated. One of the methods is digesting the gels simply. Which of the following statement is not correct in with respect to it? Correct Answer The DNA can be extracted via the addition of sodium or any positively charged group

For the method of solubilising DNA, the gelling temperature is very important. For lower gelling temperatures simply the target DNA can be sliced out and further melting is done. But for higher gelling temperatures, either agarase or chaotropic agents are added. After this, the required DNA is obtained via purification which is done by the addition of silica or solvent extraction can also be done.
