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

  • 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

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.
