Genetic Modification
Biology: IB Diploma Higher Level, topic 13.3.5
Genetic Modification
The universal nature of the genetic code means that genes can be artificially transferred between species in order to give a species a particular characteristic.
The genetic code
- The genetic code is universal.
- All species use the same genetic code and will produce the same proteins from the same genes.
- The same mRNA codon codes for the same amino acid in almost every species.
Genetic modification
- The universal nature of the genetic code means we are able to insert genes from one species into another and have them produce a protein to give that species a specific trait or characteristic.
- Some important examples of genetic modification are adding the human insulin gene to bacteria, adding the spider silk gene to goats, and adding the beta carotene gene to rice.
