Enzyme Complex Could be Key to New Cancer Treatments (1 of 2) (IMAGE)
Caption
In these microscopic images of cells, the white areas indicate the presence of enzymes. The enzymes in images A and C are distributed throughout the cytoplasm because these cells were grown in the presence of purines. In contrast, the enzymes in images B and D occur in small clusters because these cells were grown in the absence of purines.
