4/16/10 1. A soluble molecule capable of specifying more than one cell type by forming a concentration gradient is known as a: a) Gap gene b) Homeotic gene c) Cyclin d) Pair-rule gene e) Morphogen 2. The determinant that localizes bicoid mRNA to the anterior pole resides in the: a) 5’ untranslated region b) 3’ untranslated region c) Homeobox domain d) Leader sequence e) Coding region 3. You have identified a new gene involved in Drosophila embryonic patterning. When you perform the in situ hybridization to detect the mRNA distribution of this gene, you find that it is expressed in 7 stripes. Based on this observation, you can conclude that: a) This is likely a maternal-effect gene b) This is likely a gap gene c) This is likely a pair-rule gene d) This is likely a segmental-polarity gene e) This is likely a homeotic gene 4. In C. elegans vulva development, which of the following pathway is critical in determining the anchor cell from Z1.ppp and Z4.aaa cells? a) The Notch pathway
