The DNA Is then precipitated by adding isopropanol on the higher-focus salt solution. This forces the big genomic DNA molecules outside of Alternative, whilst the smaller RNA fragments remain soluble. The insoluble DNA is then pelleted and divided from salt, isopropanol and RNA fragments through centrifugation.
