PCR
PCR (Polymerase Chain Reaction) is a laboratory technique used to amplify specific DNA sequences, enabling the production of millions of copies from a small initial sample. It involves repeated cycles of heating and cooling to denature DNA, anneal primers, and extend new strands using a heat-stable DNA polymerase. This technology is fundamental in molecular biology, genetics, diagnostics, and forensic science.
Developers should learn PCR when working in bioinformatics, computational biology, or biotechnology fields that require DNA analysis, such as genome sequencing, genetic testing, or pathogen detection. It is essential for tasks like data generation from biological samples, validating genetic algorithms, or developing software for laboratory automation and analysis pipelines.
