Defying Expectations (IMAGE) Rockefeller University Caption When 3' UTR sequences of Sox 11 mRNA in embryonic mouse brain (above) were marked in red and coding sequences in green, common thinking suggested all Sox11-expressing cells would appear yellow, indicating both components were present in even ratios. Surprisingly, some cells were clearly red and others green, suggesting disparities between the two.
