he discovery of the genes that are responsible for Alzheimer’s disease</h3>
Explanation:
Biology is the study of Life and living organisms. Any person associated with research or scientific studies of living organism is directly related to careers in biology.
Alzheimer's disease is a genetic defect caused in living beings. The genes causing this disease are:
- Amyloid precursor protein (APP)
- Presenilin 1 (PSEN1)
- Presenilin 2 (PSEN2)
Due to mutation of these genes the nerve cells get damaged and patients begin to show the symptoms usually at the age of 60 and above. The genetic test results can help in early prevention and cure to Alzheimer's disease. Though research is being continued to find if there are more genes involved.
