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?

The gelling temperature has an important role to play

For higher gelling temperatures, digestion of DNA is done via the addition of agarase or some chaotropic agents

For lower gelling temperatures, simply slicing out of target DNA is done which is followed by melting

The DNA can be extracted via the addition of sodium or any positively charged group

If the amount of agarose added is more, the molecular under analysis should have the following characteristic:

size has no relation with the amount of agarose

the amount of molecules under analysis matters

The charge present on the DNA backbone is negative. The force required to accelerate the molecules towards anode is directly proportional to the number of ____________

both phosphate group and sugar molecules
