Introduction
to the Polymerase Chain Reaction (PCR): |
Gene cloning is an important tool for studying the genes that enable bacteria to cause disease. One of the most commonly used techniques for gene cloning involves the polymerase chain reaction (PCR) |
What
is PCR?
PCR is a molecular biology technique for amplifying (or copying)
a piece of DNA many times in the lab. It has many applications including:
|
- detection of hereditary
disease
- diagnosis of infectious
diseases
- gene cloning
|
- paternity
testing
- crime scenes
- ancient DNA
|
After
20 PCR cycles, the target molecule will have amplified by over
1 billion-fold! |
