The Human Genome is the complete set of genetic information for humans, consisting of approximately 3 billion DNA base pairs. It contains around 20,000 to 25,000 genes, which are segments of DNA that provide instructions for making proteins essential for the body's functions. The Human Genome Project, completed in 2003, was a landmark scientific endeavor that mapped the entire human genome, enhancing our understanding of genetics and human biology. Studying the human genome helps researchers identify genetic variations linked to diseases and traits. This knowledge can lead to advancements in personalized medicine, where treatments are tailored to an individual's genetic makeup, improving health outcomes and disease prevention strategies.
