The Why of Salt

Submitted by LifeSciTeacher (guest) on Sat, 05/28/2016 - 2:53am.

Thank you for all of this! The why for the salt mentioned above is to shield the negative charges so the DNA will precipitate. I have been telling my students that the salt in the buffer is to break down the Proteins that the DNA winds around (histones). Am I passing on a misconception?

Thanks!
