This process is important when the available DNA is too small for analysis. PCR uses Taq DNA polymerase, an enzyme that works well in high temperatures, to replicate DNA. A machine called a thermocycler controls the temperature changes needed for the process. PCR is essential in biotechnology and is part of the <a href=\"https:\/\/infinitylearn.com\/surge\/cbse\/cbse-class-12-biology-syllabus\/\"><strong>CBSE Biology syllabus<\/strong><\/a>.

By replicating DNA sequences in a test tube, PCR allows for the creation of millions of copies of a target DNA fragment, which is crucial for further analysis. The process involves three key steps: denaturation, annealing, and extension, with the help of the enzyme Taq DNA polymerase. PCR has wide applications in genetic research, diagnostics, forensic science, and medical fields, including the detection of genetic disorders.<\/p>\n<p>For Class 12 Biology, understanding PCR is essential as it forms a part of the syllabus and helps in answering questions related to biotechnology, genetics, and molecular biology. A solid grasp of PCR can significantly enhance a student\u2019s ability to tackle related topics in the Class 12 and NEET exam.<\/p>\n<h2>PCR (Polymerase Chain Reaction) MCQ with Answers<\/h2>\n<p><strong>Q1.
