The DNA Is then precipitated by adding isopropanol towards the substantial-concentration salt Remedy. This forces the big genomic DNA molecules from Remedy, although the smaller RNA fragments continue to be soluble. The insoluble DNA is then pelleted and separated from salt, isopropanol and RNA fragments by way of centrifugation.
