- Classification Using DNA and Proteins
- Genome Sequencing
- DNA base sequence of one organism is compared with another to see how closely related the two organisms are
- Closely related species will have a higher percentage of similarity in their DNA eg. humans and chimps share around 94%
- Differences in the DNA base sequence result in a difference in the proteins produce.
- Comparing Amino Acid Sequence
- The sequence of amino acids in a protein is coded for by the base sequence in DNA.
- Related organisms have similar DNA sequences and so similar amino acids in their proteins.
- Immunological Comparison
- Similar proteins will also bind to the same antibodies.
- Example- If antibodies of a human are added to isolated samples of proteins from other species, any protein similar to the human will be recognized by the antibody
