1. Denaturation (separation of two strands of DNA by temperatures of around 94 to 98 degrees Celsius)
2. Annealing (binding of DNA primer to the separated strands. Occurs at 50 to 65 degrees Celsius, which is lower than the optimal temperature of the DNA polymerases)
3. Elongation (elongation of the strands using the DNA primer with heat-stable DNA polymerases, most frequently Taq (Thermus aquaticus) or Pfu (Pyrococcus furiosus) polymerases. Occurs at over 70 degrees Celsius)

What is pcr and types of pcr?
PCR is a biotechnological method to amplify your gene (DNA) of your interest. It produce millions of your DNA fragments hence used in cloning. There are variants of this method using the same thermocycling principle such as touch down PCR, gradient PCR, RFLP, multiplex PCR, Q PCR, RT PCR and so on.
Why is PCR called a chain reaction?
PCR is called a chain reaction because it involves the repeated cycling of three main steps (denaturation, annealing, and extension) to exponentially amplify a specific DNA sequence. Each round of these steps creates new copies of the target DNA, leading to a chain reaction that greatly increases the amount of DNA available for analysis.
How to perform PCR effectively for accurate results?
To perform PCR effectively for accurate results, follow these steps: Prepare a clean work area and gather all necessary materials. Diligently follow the PCR protocol, including proper handling of reagents and samples. Use high-quality DNA templates and primers to ensure specificity and efficiency. Set up the PCR reaction carefully, including appropriate cycling conditions and controls. Maintain proper temperature and time parameters during the PCR process. Analyze the results accurately using gel electrophoresis or other appropriate methods. Document all steps and results meticulously for reproducibility and troubleshooting if needed.
In a pcr reaction of DNA are first separated by?
In a PCR reaction, the DNA strands are first separated by heating the sample to a high temperature (usually around 95°C), which breaks the hydrogen bonds between the two strands and results in denaturation. This step is necessary to allow the primers to bind to their complementary sequences during the subsequent steps of the PCR process.
What is the use of dNTP?
The use of dNTP is PCR and multiplex PCR
What does a thermocycler do and how does it contribute to the process of polymerase chain reaction (PCR)?
A thermocycler is a machine that controls temperature changes during the polymerase chain reaction (PCR) process. It heats and cools the reaction mixture to specific temperatures required for DNA replication. This precise temperature control is essential for the PCR process to work efficiently and accurately by facilitating the denaturation, annealing, and extension steps of DNA amplification.
