10.) What are the three properties of Enhancers? 11.) Name the (4) conserved motifs of transcription factors. 12.) Describe (briefly) the difference of what happens if an miRNA is 100% complementary to a target sequence or if it is only partially complementary. Solution 1. Enhancer is a small region of DNA that can be bound by proteins to increase the likelihood that transcription of the particular gene will occur. Three properties of enhancers are as follows: 2. Helix-Turn-Helix motif, Zinc finger motif, Leucine zipper motif, and Helix-loop-Helix motif. 3. If miRNA is 100% complementary to the target sequence, the protein expressed will be correct and there will be no repression in the process of gene expression while if it is partially complementary, it induces gene repression through cleavage of target transcripts..
