The Human Genome Project (HGP) was a landmark scientific endeavor that mapped the entire human genome, providing invaluable insights into our genetic makeup. Understanding our DNA has profound implications for medicine, biology, and genetics. Here’s an overview of the HGP and its impact.

1. The Goals and Achievements of the HGP

The HGP aimed to identify all the genes in human DNA and determine the sequences of the three billion base pairs that make up the genome. Completed in 2003, the project has achieved several key milestones:

  • Gene Identification: The HGP identified approximately 20,000-25,000 human genes.
  • Genome Sequencing: The complete sequence of the human genome was determined, providing a reference for genetic research.
