  • -Extract the genome of the budding yeast as the template used in the subsequence PCR, yeast stains was Saccharomyces cerevisiae laboratory strain W303 (haploid), and the extraction procedure is based on the fungal genome extraction kit(Omega Bio-Tec).
    -Poor yield, partly because the yeast concentration in the suspension is low for genome extraction. The time for yeast incubation should be prolong for extraction next time.
