Figure 1From: Ploidy influences cellular responses to gross chromosomal rearrangements in saccharomyces cerevisiaeThe various types of GCRs selected using the positive selection screening method based on the URA2 gene. Green rectangles stand for chromosome X, whereas pink rectangles indicate another chromosome. Black circles stand for centromeres and red squares for the URA2 gene. This gene contains 3 mutations (indicated by crosses) responsible for auxotrophy towards uracil.Back to article page
