Higher The Human Genome Project and Its Applications
The Human Genome Project (completed 2003) was an international collaboration that sequenced all 3.2 billion base pairs of human DNA. Key outcomes and applications include:
- Disease gene identification: Thousands of genes linked to conditions such as breast cancer (BRCA1/2), Huntington's disease, and cystic fibrosis have been mapped, enabling genetic testing and risk assessment.
- Personalised medicine: Knowing a patient's genome allows doctors to select treatments that will be most effective for their particular genetic profile (pharmacogenomics).
- Evolutionary relationships: Comparing human genome sequences with those of other species reveals shared ancestry — humans share approximately 99% of their DNA with chimpanzees and around 60% with fruit flies.
- Ethical considerations: Genome data raises questions about genetic privacy, insurance discrimination, and the ethics of genetic selection. These are areas of ongoing debate in bioethics.
