The DNA is then precipitated by including isopropanol for the substantial-concentration salt Remedy. This forces the big genomic DNA molecules from Remedy, even though 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. https://rna-purification-beads05825.pennywiki.com/4141008/the_2_minute_rule_for_dna_rna_purification
