What was the goal of the Human Genome Project?

• A. A clinical trial for gene therapy.
• B. A program for vaccine development.
• C. An observational study of genetic diseases.
• D. A research project that mapped all human genes.

Answer: (D)

The main idea is to map and sequence the entire human genome and create a reference genome that shows where genes are located and what their DNA sequences are. This foundational map would let researchers identify genes, understand their functions, and study how genetic variation influences health and disease across people. It wasn’t about testing a treatment or producing vaccines; it was about building a comprehensive blueprint of human DNA to guide future biology and medicine. The project aimed to produce a complete, ordered sequence of all human DNA bases with gene annotations, enabling countless studies and new technologies. Other options describe different kinds of studies or interventions, not the ambitious goal of creating the full genomic blueprint.
