​process (2012)

Easier to edit DNA and insert genes (<15 minutes)

Clustered Regularily Interspaced Short Palendromic Repeats (CRISPR)

Rapid duplication of DNA

Doubles each cycle

• ​Useful for small samples

  • COVID Testing

  • Crime scene DNA

Polymerase Chain Reaction (PCR)

Sometimes called DNA fingerprinting

Gel Electrophoresis

Short repeated segments of DNA

​Differ between people

Currently, 13 are used

• Leads to a probability of match of 1 in one quintillion (10¹⁸)

STRs (Short tandem repeats)
