Yeast genomic DNA isolation (Table 1) Yeast colonies were picked from complete medium (CM) selective plates lacking amino acid lysine after two days growth at 30°C. In contrast, cell lysis in the alkaline lysis method results in all material including genomic and plasmid DNA release in the solution. The high concentration of sodium hydroxid e denatures the genomic and plasmid DNA, as well as cellular proteins. The cellular DNA becomes linearized and the strands are separated, whereas the plasmid DNA is circular and remains topologically constrained (the two strands, although denatured remain together). The lasted time to extract DNA from bacteria was roughly estimated in 30 min. 10 QIAGEN Genomic DNA Handbook 04/2012 used to isolate up to 225 μg or 750 μg of DNA, respectively, in under an hour.
