Genome

• A genome is the entire genetic information of an organism.
• There are over 21000 genes in a human genome.
• Genome allows us to:

  • search for genes linked to certain genetic diseases
  • understand inherited disorders + treatments
  • trace human migration patterns
• By looking at an individual's genome we can predict how they will respond to certain drugs.
• Medical research: with genomes we can compare inherited disease with unaffected genes to learn causes and precise mutations.
• Personalised medicine: we can identify the risk of certain diseases due to genetics and give advice of preventative treatments.
• Forensic science: DNA profiling uses variations in our genome to match individuals to crime scenes, victims or suspects.
• The Human Genome Project can be used as evidence for evolution - we can trace back human migration patterns.
• Phylogenetics is comparing gene sequences between species to show evolutionary relation or comparing gene sequences between modern and ancestral humans to collect evidence for migration.
