Briefly describe molecularly what makes a cell or organisms specification autonomous vs. conditional.  Do not just define autonomous vs. conditional, but discuss what determines if a cell would have autonomous vs. conditional specification  (3 pts):  

Which of the following is the minimum set of combinatorial transcription factor binding elements for the enhancer that drives specific expression of the starred pair-rule stripe in the lower image.  This corresponds to the starred area in the upper image, which represents the gap genes available at the time of expression of the pair-rule genes:

General understanding questions: In order to determine the effects of different types of mesenchyme on differentiation of various types of epithelia, a biologist performed transplantation studies by separating and then combining the epithelial and mesenchymal portions of salivary glands, mammary glands, and pancreas, and obtained the following morphological results.      Salivary mesenchyme + Salivary epithelium –> salivary gland Salivary mesenchyme + Pancreatic epithelium –> salivary gland Salivary mesenchyme + Mammary epithelium –> salivary gland Pancreatic mesenchyme + Pancreatic epithelium –> pancreas Pancreatic mesenchyme + Salivary epithelium –> no differentiation no mesenchyme + any of the three epithelium –> no differentiation Which of the following can be concluded from this experiment, based on the responses of salivary, pancreatic, and mammary epithelia to transplanted mesenchyme?

A particular gene in Drosophila is essential for proper embryonic development. However, it is not active in embryonic cells at all times during growth. The Western (protein) and Northern (mRNA) blots below show expression of this homeotic gene at various points during development in drosophila. This will tell you if the mRNA (Northern) and/or the protein (Western blot) are expressed in the egg or embryo at any given time.  The entire embryo was used to obtain protein (Western blot) or mRNA (Northern blot). (Embryo age = hours) At what stage of development does transcriptional activation of the embryo’s own genome become active for this particular gene?
