Study Notes
DNA Discovery
- DNA is composed of a double helix structure
- DNA is the chemical substance within cells that determines hereditary patterns in all living things.
- Working out its structure helps scientists learn how DNA replicates and passes on genetic information and provides insight into how genes work.
The DNA Race
- The race to discover the structure of DNA began before Watson and Crick met in 1951
- In 1944, Oswald Avery discovered that DNA carries genetic information.
Discovering the Double Helix
- The discovery of the DNA's double helix structure enabled the launch of new scientific techniques such as gene sequencing and genetic engineering.
- It also opened up vast areas of research into inherited medical conditions.
