6b. Look at Figure 4.7, which depicts the loss of oxygen over time and the transcriptional response of three genes. These data are the ratios of transcription for genes X, Y, and Z during the depletion of oxygen. Using the color scale from Figure 4.6 (bright, medium, dim green, black, dim, medium, or bright red), determine the color for each ratio in Figure 4.7b.
This question falls on the pages before it discusses the log transform. Therefore I assume we are to use the ratio values and determine the fold repression of the values less than 1.0 (red) using the equation Fold repression = 1/ratio
