Specifically altered metaphase chromosomes in antifolate-resistant Chinese hamster cells that overproduce dihydrofolate reductase

Erratum Specifically Altered Metaphase Chromosomes in Antifolate-resistant Chinese Hamster Cells that Overproduce Dihydrofolate Reductase. J. L. Biedler, P. W. Melera, and B. A. Spengler (in Cancer Genetics and Cytogenetics 2, 47-60, 1980) Figures 2 and 3 were altered during printing. In Figure 2 a bracket was deleted from the chromosome designated (h). In both figures the photographic background left around each chromosome was unevenly blanked out, effectively adding terminal bands, e.g., Figure 2, (f) and (g); Figure 3, (e), or appearing to cut off parts of chromosomes, e.g., Figure 2, normal chromosome 2 and (h). The figures appear in their correct form below.
