Presentation Transcript

  1. The polymerase chain reaction (PCR) rapidly copies segments of DNA.

  2. target sequence of DNA PCR uses polymerases to copy DNA segments. • PCR makes many copies of a specific DNA sequence in a few hours. • PCR amplifies DNA samples. • PCR is similar to DNA replication.

  3. DNA strands primer1 polymerase primer 2 nucleotides PCR uses four materials • DNA to be copied • DNA polymerase • A, T, C, and G nucleotides • two primers

  4. DNA strands primer1 polymerase primer 2 nucleotides The three steps of PCR occur in a cycle. • heat is used to separate double-stranded DNA molecules • primers bind to each DNA strand on opposite ends of the segment to be copied • DNA polymerase binds nucleotides together to form new strands of DNA

  5. Each PCR cycle doubles the number of DNA molecules.
