Real time PCR MCQs Welcome to your Real time PCR quiz. 1. Which of the following is true for traditional and real time PCR? Both the techniques allow detection of the product in early stages Real time PCR can detect the product in early stages as compared to traditional PCR Both systems require different primers Both techniques are end point product determination methods None 2. Which of the following method is not the application of real time PCR? Gene copy number detection Determination of the viral load in a sample RNA expression profilling Chromosome number detection None 3. What is the role of RNase inhibitor in real time PCR methods? In cDNA synthesis Protection of RNA from degradation by enzyme To stop the spontaneous degradation of the product All of the above None 4. How primer concentration leads to decrease in PCR efficiency? Primer concentration decreases with time Binding specificity of the primer reduces over cycles Base pairing between the primers reduces their availability Excess template leads to competition for primer None 5. What is pattern of the graph, PCR product vs time in real time PCR? Exponential Linear Both None None 6. Which of the following is important in real time PCR based gene expression study? Primer designing Conversion of RNA to cDNA Isolation of RNA Protecting RNA from degradation All of the above None 7. Which of the following technique is not used for gene expression studies?
