PCR consists of several cycles of 3 steps: denaturing, annealing, and extension. Which of the following is a consideration when planning a PCR reaction? a) The denaturation temperature may be adjusted based on the GC content of the primers b) The extension temperature may be adjusted based on the GC content of the primers c) The annealing time may be adjusted depending on the length of the sequence to be amplified d) The extension time may be adjusted depending on the length of the sequence to be amplified e) The extension temperature may be adjusted based on the GC content of the template 2. Which statement is not true about Telomerase? a) it is brought to chromosome ends by Sheltrin b) it extends the 3' end of a chromosome using its RNA component as a template c) if it is not present, chromosomes will shorten every time they replicate d) it is related to the viral RNA-dependent RNA polymerase found in some RNA viruses e) it generates a single-stranded DNA sequence at chromosome ends that then serves as a template for RNA primase and DNA polymerase 3. Which of the following is added to cells when making mutants by CRISPR/Cas9-mediated site-directed mutagenesis? - Note both of these answers are correct. Everyone is given 1 mark for this regardless of what they chose. a) cas1/2 endonucleases b) a pre-CRISPR RNA c) a guide RNA comprised of a CRISPR RNA plus a PAM sequence d) cas9 protein e) all of the above 4. To perform RNAi on human cells, a siRNA is introduced into the cells. What else has to be introduced into the cells to allow for gene knockdown? a) Dicer b) Cas9 c) RISC d) both a and c e) none of the above 5. What is a good explanation for why individuals with XPG mutations are prone to cancer? a) their transcription-coupled repair pathway is non-functional and therefore RNA polymerase often cannot transcribe important genes b) in the absence of nucleotide excision repair pathway, cells undergo apoptosis c) both branches of the nucleotide excision repair pathway are inactive and therefore pyrimidine dimers are not repaired, leading to failure to replicate DNA d) the cell relies on the error-prone translesion DNA polymerase to synthesize DNA past pyrimidine dimers
