• hydrogen bonds between nitrogen bases

The genetic code describes the way that information is coded in DNA. This code is -

• determined by organism’s environment

• the same among all living organisms

The genetic code seems to suggest that all organisms are related. This conclusion is based on the fact that –

• each species has some form of a code

• every living thing uses the same code
