The major groups of organisms that have cryptochrome based on the fact that it is found in both animals and plants derived from their common ancestor. Introduction: A class of flavoproteins that is sensitive toward blue light is cryptochromes. Flavoproteins are proteins having riboflavin derivative of nucleic acid . These cryptochromes are involved in circadian rhythm. There are two genes responsible for coding the cryptochrome protein, Cry1 and Cry2. In plants, this protein is responsible for mediating phototropism and photomorphogenesis. In animals, it is involved in capturing light and other circadian rhythms.

You’re curious about the effect that gap genes have on the pair-rule gene, evenskipped (eve), so you isolate and sequence each of the eve enhancers. You’re particularly interested in one of the enhancers, which is just upstream of the eve gene. Describe an experimental technique you would use to find out where this particular eve enhancer is active.
