  1. Eukaryotic DNA methylation is most commonly observed at which of the following sequences? 1. GATC 2. TC ✓ 3. CG 4. AC 5. TATA

  2. Which of the following is not a cis-regulatory element? 1. Promoter 2. GC box 3. silencer ✓ 4. TFIID 5. UAS

  3. Which of the following statements about enhancers is not true? ✓ 1. They only work in one orientation 2. They can be located many kb upstream of the genes they regulate 3. They can be located within introns 4. If a second gene is placed next to an enhancer, transcription of the additional gene will also be elevated

  4. In the regulation of genes for galactose (GAL) metabolism, which of the following is the transcriptional activator? 1. UAS 2. Gal80p 3. Gal3p ✓ 4. Gal4p

  5. Nonsense-mediated decay refers to the process whereby 1. an mRNA is targeted for degradation by enzymes that shorten the poly-A tail 2. an mRNA is targeted for degradation by removal of the 5' cap 3. an mRNA is targeted for degradation by the RNA interference pathway ✓ 4. an mRNA is targeted for degradation after the ribosome stalls at a premature stop codon

  6. The protein complex that binds to long double-stranded RNA (dsRNA) and cleaves it into smaller 21-23 nt pieces is called 1. RISC ✓ 2. Dicer 3. TBP 4. RITS
