How to Make Billions of Copies of a DNA Segment

This patent describes the Polymerase Chain Reaction (PCR), a method to rapidly create many copies of a specific piece of DNA or RNA, enabling its detection and analysis.

How to Make Many Copies of a DNA Piece with Heat

This patent describes the Polymerase Chain Reaction (PCR) method, a technique to make millions of copies of a specific DNA segment using a heat-resistant enzyme and repeated temperature changes.

How to Make Many Copies of a Specific DNA Segment

This patent describes the fundamental three-step process for making millions of copies of a specific piece of DNA using short starter molecules and an enzyme, a technique known as Polymerase Chain Reaction (PCR).

Detecting Genetic Differences Using DNA Probes and Enzymes

This 1987 patent describes a method to find tiny differences in DNA sequences by using special DNA pieces (probes) and cutting enzymes, which can help diagnose genetic conditions like sickle cell anemia.

Using Heat-Resistant Enzymes to Read DNA Sequences Faster

This patent describes using a heat-stable enzyme from a bacterium that lives in hot springs to make the process of reading DNA code much more reliable and efficient.
