Timeline of major events in biology leading to Genetic Engineering

1. Mendel's discoveries about the nature of inheritance

2. The discovery that chromosomes carry genetic information

3. Elucidation of DNA as the genetic molecule

4.Discovery of the structure of DNA

5.Research on DNA replication and repair

6.Discovery of restriction enzymes

7.Discovery of heat-stable DNA polymerase

How these discoveries affect you:

1.Medical diagnoses

2.Medical byproducts (e.g., insulin, human growth hormone, cancer drugs)

3.Forensic DNA studies (evidence in courts of law)

4.Genetically-engineered crops and animals
