Concept explainers
To describe: The reasons behind the revolutionary concept of PCR.
Introduction: A process of molecular biology which is responsible for the production of various copies of a particular segment of DNA is called “polymerase chain reaction (PCR).” Using the technique of PCR, a single segment of DNA can be amplified to produce a sufficient number of copies of that particular segment.
To describe: The two applications of PCR.

- (i) (ii) What is the major difference between the conventional PCR and real time PCR (qPCR) in terms of function? SyBR green and Taqman dyes are usually utilized in real time PCR. Which dye is more sensitive and accurate? Explain your answer.arrow_forwardMake the PCR Cocktail This table lists the ingredients, stock reagent concentrations, and concentrations in the PCR reaction. Prepare a "PCR cocktail" to be added to your samples to achieve these concentrations. Make enough cocktail to run nine samples. [Four student samples + three positive controls + one negative control + one extra.] {Hint: Remember that the concentration in the reaction is not the same as the concentration in the cocktail!] Component Stock Concentration Concentration in the PCR reaction Volume per reaction Volume to make cocktail Sterile water - - µl µl PCR buffer w/ MgCl2 10x 1x µl µl Nucleotide mix 10 mM 0.2 mM µl µl Primer 1 (Forward) 10 µM 1.0 µM µl µl Primer 2 (Reverse) 10 µM 1.0 µM µl µl Taq DNA polymerase 5 U/µl 1.0 U µl µl DNA template (sample) - ~1 ng 20 µl µl Total - - 40 µl µlarrow_forwardIn PCR amplification Why is it important to know the length of the sequence you amplify?arrow_forward
- Polymerase Chain Reaction (PCR) was invented by Kary Mullis in 1983. This technique had indeed facilitated research in various areas of molecular biology and genetics. You would like to amplify a particular gene fragment from the yeast genome using Polymerase Chain Reaction (PCR). What are the THREE (3) main cycles in PCR? Discuss the processes at each PCR cycle mentioned.arrow_forwardPCR is quick, efficient and easy to perform. However, there are some situations when cell-based cloning is preferred over PCR to amplify a DNA sequence. Mention two of them.arrow_forwardTOPIC: PCR and Gene Cloning Basics Question: What are 2 possible roles of CaCl2 in the transformation process?arrow_forward
- Cloned Libraries You are running a PCR to generate copies of a fragment of the cystic fibrosis (CF) gene. Beginning with two copies at the start, how much of an amplification of this fragment will be present after six cycles in the PCR machine?arrow_forwardWhat is the difference between PCR and real-time PCR, and how do you explain it?arrow_forwardWhat's the main difference between first-generation sequencing, second-generation sequencing and whole genome amplification.arrow_forward
- Describe PCR. Give a real world example of when PCR may be used in the lab to solve a problem. Do a little research if nothing comes into your mind.
