Polymerase chain reaction powerpoint

  1. 1. Polymerase Chain Reaction By Whitney Housley
  2. 2. Definition-• The polymerase chain reaction aka PCR is a method used to analyze a short sequence of DNA or RNA, it is used to reproduce selected sections or DNA or RNA
  3. 3. Steps
  4. 4. Advantages• Much faster than using vectors• Only a little bit of target DNA is needed
  5. 5. Disadvantages• Are to synthesize primers, we need to know the sequence flanking the DNA segment of interest• Only applies to short DNA fragments, mostly less than 5 kb
  6. 6. What is it used for?• Medical and biological research• Cloning• Diagnosis of hereditary diseases• Identification of fingerprints• Forensic sciences• Paternity testing• Diagnosis of infectious diseases
  7. 7. Cited Sources• Mrs. Scherman’s Honors Biology Class Notes• <>.• < se_chain_reaction/article.htm>.
