The polymerase chain reaction (PCR) technique allows for rapid amplification of specific DNA fragments. PCR uses primers, DNA polymerase, and repeated heating and cooling to denature and renature DNA, resulting in exponential accumulation of target sequences. Over 20-30 cycles of denaturation, annealing of primers, and extension by DNA polymerase can produce millions of copies of the target DNA fragment from only a trace amount of starting material. PCR has many applications including pathogen diagnosis, mutation detection, DNA fingerprinting, and research.

Executive Directors Chat Leveraging AI for Diversity, Equity, and Inclusion
Let’s explore the intersection of technology and equity in the final session of our DEI series. Discover how AI tools, like ChatGPT, can be used to support and enhance your nonprofit's DEI initiatives. Participants will gain insights into practical AI applications and get tips for leveraging technology to advance their DEI goals.
Introduction to AI for Nonprofits with Tapp Network
Dive into the world of AI! Experts Jon Hill and Tareq Monaur will guide you through AI's role in enhancing nonprofit websites and basic marketing strategies, making it easy to understand and apply.

Pcr (polymerase chain reaction)
- 2. INTRODUCTION • Pcr technique was developed by Kary mullis, califormia (1985) • This technique has made it possible to synthesize large quantities of DNA fragments without its cloning • It is ideally suited where the quantity of biological specimen available is very low such as a single fragment of hair or a tiny blood stain left at the site of a crime
- 3. Requirements DNA Templates: any source that contain one or more target DNA molecules to be amplified can be taken as template Primer: A pair of oligonucleotides of about 180-300 nucleotides with similar G+C content act as a primer The primers are designed to anneal on opposite strands of target sequence so that they will extended towards each other by addition of nucleotide to their 3’ end Enzymes: Enzyme is thermostable called Taq polymerase isolated from Thermus aquaticus and vent polymerase from thermococcus litoralis It survives at 95⁰c for 1-2 mins & has a half life of more than 2 hrs
- 4. WORKING MECHANISM OF PCR Denaturation: The target DNA (sequence of 100-5000 bases) to be amplified is heated denaturated (95⁰c for 15 sec) to separate its complementary strands. This process is called melting of target DNA A separation each strand act as template for DNA synthesis
- 5. Primer annealing: Annealing of two oligonucleotide primers to the denatured DNA strands Since nucleotide sequence of each of oligonucleotide primer is complementary to 3’end of single stranded template Primers are added in excess and the temperature lowered to about 68⁰c for 60 sec
- 7. Primer extension: Nucleotide tri-phosphate (dATP, dGTP, dCTP, dTTP) and a thermostable DNA polymerase are added to the reaction mixture The DNA polymerase accelerate the polymerization process of primer at 68⁰c reasulting in synthesis of copies of target DNA sequence The concentration of Mgᶧᶧ is maintained between 1 & 4 Mm
- 8. Thus in the first step the target DNA is copied from the primer sites for various distance untill the start of second cycle However, after completion of one cycle the targeted sequence on both strands are copied and four strands are produced Now, the first cycle is repeated which yields eight copies from four strands The second cycle is started with heating of double stranded DNA to result in single stranded DNA
- 9. Similarly, the third cycle produces 16 strands. This cycle is repeated about 50 times Theoretically, 20 cycles (each of 3 steps) will produce about one million copies of target DNA sequence & 30 cycles will produce one billon copies For the working of PCR about 10-100 picomoles of primers are required The PCR machine carryout 25 cycles & amplify DNA 10⁵ times in 75 minutes
