Summary Introduction

To explain:

The way by which polymerase chain reaction is used to amplify specific DNA sequence.

Introduction:

PCR (polymerase chain reaction) is a technique used in molecular biology to amplify a single copy or few copies of segment of DNA to synthesize the new strand of DNA. PCR is used to make copies of DNA. It is of many types like, real time PCR, nested PCR, and semi- nested PCR. PCR is having three main steps that are denaturing, annealing, and extension. PCR reaction contains template DNA, primers, deoxynucleotide triphosphates, DNA polymerase, Mg 2+ ions, and buffer.

Summary Introduction

To determine:

The limitation of the PCR.

Introduction:

PCR is polymerase chain reaction, which make many copies of DNA from a single copy of DNA. It takes place in 3 steps: denaturation, annealing, and extension. PCR is fast, accurate and best method to amplify DNA. It has some limitation like, taq polymerase enzyme is unable to carry out the process of proof-reading, and it only makes copies up to 20,000 base pair.

Awnser these Discussion Questions Answer these discussion questions and submit them as part of your lab report. Part A: The Effect of Temperature on Enzyme Activity Graph the volume of oxygen produced against the temperature of the solution. How is the oxygen production in 30 seconds related to the rate of the reaction? At what temperature is the rate of reaction the highest? Lowest? Explain. Why might the enzyme activity decrease at very high temperatures? Why might a high fever be dangerous to humans? What is the optimal temperature for enzymes in the human body? Part B: The Effect of pH on Enzyme Activity Graph the volume of oxygen produced against the pH of the solution. At what pH is the rate of reaction the highest? Lowest? Explain. Why does changing the pH affect the enzyme activity? Research the enzyme catalase. What is its function in the human body? What is the optimal pH for the following enzymes found in the human body? Explain. (catalase, lipase (in your stomach),…
