Mаternаlly depоsited mRNAs fоrm the embryоnic protein grаdients shown below, and these gradients directly regulate expression of the earliest zygotic genes in Drosophila. Below are diagrams of wild-type Drosophila embryos, with the anterior on the left, posterior on the right. The blue stain shows the location of zygotic gene expression. Choose the embryonic expression pattern (A through I) that is predicted by each described regulatory system. 1. [answer1] This gene is transcriptionally activated by Caudal or Hunchback, but when Caudal and Hunchback are present together, the transcription factors change to be repressors. 2. [answer2] This gene is transcriptionally activated by Bicoid binding to a low-affinity cis regulatory sequence. 3. [answer3] This gene is transcriptionally activated by Caudal, and the cis regulatory sequence on this gene has high affinity for Caudal.
