Key Concepts & Definitions

  • In Vitro DNA amplification: A cell-free method developed in 1980 that allows rapid, reliable, and versatile amplification of specific DNA sequences, enabling parallel processing and revolutionizing genetics (source content).
  • PCR (Polymerase Chain Reaction): A technique that amplifies specific DNA sequences exponentially through cycles of denaturation, annealing, and extension, using DNA polymerase to produce billions of copies (source content).
  • DNA cloning: The process of transferring DNA sequences into target cells, where they undergo proliferation, resulting in DNA amplification within intact cells (source content).
  • Selective amplification of DNA sequences: The process of amplifying only specific DNA regions of interest, often achieved through primer design and hybridization techniques, to isolate particular genetic material (source content).
  • Use of DNA polymerase to make multiple copies: An enzyme that synthesizes new DNA strands from a template during PCR, essential for the exponential amplification process (source content).
