5) p points) Temperature regulation is critical while preforming PCR. What could resuit IT the PCR reaction is not cooled to 42°C -65°C before the extension step? Why would this occur (2 points) If you start with one copy of a single gene of interest and perform PCR on that sequence, how many copies of the gene would you have after 10 cycles? Explain your reasoning.

A researcher is doing a PCR-based experiment using the following temperature profile: • Melt for 1 minute at 94°C • Anneal for 30 seconds at 37°C Extend for 30 seconds at 70°C Unfortunately, her gels show way too many bands. Her primers have perfect complementarity to the target sequence. Give a simple way to reduce the number of bands.

This PCR step is called annealing. The annealing step follows the denaturation step: it is usually the lowest temperature in the PCR. The temperature of this step varies with each PCR reaction because each primer has its own sequence and may not be an identical match to the DNA template strand. GC or CG have three hydrogen bonds and AT or TA have two hydrogen bonds. Higher annealing temperatures are more stringent and require a better match between primer and...

Which of the following is NOT a reason that each PCR Primer requires a different PCR settings? -because the complimentary strands of the DNA may be composed of more G-C pairs which would require less energy to denature than a strand with more A-T pairs due to the amounts of hydrogen bonds to break in each. -because the PCR products are different lengths which may require different amounts of time to denature, elongate , and extend the PCR...

Problem.1: What does a PCR optimization means? Problem.2: You are working on a gradient PCR to determine the optimum annealing temperature for your primer, and you get the following result. Problem.5: Your target is to amplify a promoter region of TRF2 gene. You design the following primer pair: Forward: 5'- CAGCGCTGCCTGAAACTC-3: Tm: 58.6°C, length: 18 bp, GC%: 61.11% Reverse: 5'- GTCCTGCCCCTTCACCTT-3' Tm: 59°C, length: 18 bp, GC%: 61.11% Product size: 200 bp -You get the following result: Marker CC CCC...

What are some differences between the PCR that occurs in the Sherlock protocol and the PCR that occurs in RT-PCR test? O PCR in Sherlock protocol can amplify more than one gene at the same time O Dyes are added to RT-PCR PCR in RT-PCR is faster PCR in Sherlock protocol is isothermic (all the steps occur at the same temperature).
