Based on your knowledge of DNA replication and PCR, what are the other twocomponents and what are their functions?1b: Explain what would happen if the PCR reaction did not contain Taq polymerase?Assuming all other required PCR components are present, would any part of the PCRreaction occur? Explain your reasoning.1c: Why does a PCR reaction require a primer? Would you expect this primer to becomposed of DNA or RNA? Explain your reasoning.1d: Should PCR primers be complementary to each other? Explain your reasoningle: As you know, experiments include controls.

Look at each PCR component listed below. For each one, determine which steps(s) of the PCR reaction (denaturation, annealing or extension) would be directly affect if that component were missing. Taq polymerase: Oligonucleotide primers: DNA template: Deoxynucleotides (A, T, G and C): Imagine that you correctly prepare your PCR reaction mixture, but there is something wrong with the thermal cycler. Describe what would happen if: The thermal cycler was stuck on 940C: The thermal cycler cycled between 600C and 720C, but never reached 940C The thermal cycler cycled between 940C and 720C, but never reached 600
The ability to multiplex the PCR reactions used in STR analysis (many PCR amplifications occurringin the same tube at the same time) simplifies the DNA profiling technique a great deal. However,the analysis of the PCR products involves measuring only their size and their color, and this is allthe software needs to know in order to figure out which PCR products are from which locus. Howcan the analysis software tell all the various loci apart?
Polymerase Chain Reaction (PCR) works by exposing the reaction to a series of temperature changes. In 150 words or fewer, describe 1.) the different stages of a single PCR cycle, 2.) how many cycles of PCR your reactions will undergo, and 3.) why multiple cycles are necessary.

Put the steps of one PCR cycle in the correct order: The PCR reaction mixture is heated to about 70 degrees, which is the optimum temperature for the polymerase to build the new strands of DNA, starting at the 3' end of the primer. The PCR reaction mixture is heated to 95 degrees Celsius, which denatures the double stranded template DNA. The PCR reaction mixture is cooled to about 50-55 degrees, which allows the primers to find their complementary site on the template and "anneal" the
Explain why DNA ladders are usually included during gel electrophoresis. One aspect of PCR that can be modified is the annealing temperature. In general, higher annealing temperatures show more specificity towards a single template, whereas lower annealing temperatures show less specificity and may bind to multiple regions throughout the genome. Discuss how using an annealing temperature that is too high or too low might influence the results of a PCR assay (and gel electrophoresis results) such as the one used in this study.
Analyze the PCR products in Fig. 1A by describing your observations and the PCR result. Your analysis should be in maximum of 5 sentences in bullet form. Include the following in your analysis: Observations: Are bands present? If yes, what the approximate size in bp of each band? Results: Was amplifying the target gene successful?
You are working in a molecular biology laboratory and are having challenges with your PCR. You decide to double-check the PCR protocol programmed into the thermal cycler and discover that the annealing temperature was programmed to be 65 °C instead of 50 °C, as you had intended. What effects would this mistake have on the PCR reaction? Suggest potential solution(s).
The process of DNA Replication depicted in the Polymerase Chain Reaction technology. Below are steps/components in DNA replication in cells. Briefly indicate the purpose/function of the components in DNA replication at the second column. For the third column, watch a PCR video in youtube and fill the column under PCR as to what step/components in the PCR technology corresponds to the second column. Question: In Reverse Transcription PCR, what step is added the ordinary PCR? Provide short explanation in the last column.
Explain why a positive control and negative control are included in PCR experiments. Explain the three steps involved in each cycle of polymerase chain reaction.Why is loading dye added to the DNA sample for gel electrophoresis? Explain the function of the following components in a PCR reaction:− Primer, dNTP, MgCl, Taq polymerase, buffer.
Answer the following questions related to PCR Bioinformatics for DNA Extraction using Why is it necessary to chelate the metal ions from the solution during the boiling/lysis step at 100 degrees celsius? What would happen if you did not use a chelating agent such as the InstaGene matrix? What is needed from the cells for PCR? What structures must be broken to release the DNA from a cell?
PCR is a very useful method in biotechnology because it does not require the 6 or more different key proteins/enzymes required for DNA replication in living cells. Explain how and why this technique only requires 1 enzyme to make lots of DNA.
