1. 13.2 – Manipulating DNA

2. The Tools of Molecular Biology
Genetic engineering – making changes in the DNA code of a living organism
DNA extraction – by a simple chemical procedure
Cutting DNA – most DNA to large to be analyzed
Can be cut precisely at restriction enzymes
Separating DNA – gel electrophoresis

3. Using the DNA Sequence
After the DNA is shortened up it can now be read, studied and even changed
The function of different genes can now be discovered

4. Gel Electrophoresis DNA plus restriction enzyme Power source
Longer fragments
Shorter fragments
Mixture of DNA fragments
Gel
