Quantitative Polymerase Chain Reaction (qPCR)

Quantitative Polymerase Chain Reaction (qPCR) is a lab technique used to amplify and measure specific DNA sequences in a sample. It allows scientists to understand how much DNA is present by tracking the replication process in real-time. As the DNA copies increase, a special dye binds to the DNA, emitting light that can be measured. This helps researchers quantify DNA, making qPCR valuable in various fields, including genetics, medicine, and environmental science, for tasks like detecting diseases or studying genetic variations.
