Abstract

DNA sequencing and the identification of genetic markers have revolutionized the way we understand human genetics, leading to advancements in personalized medicine, disease prevention, and treatment. The ability to sequence entire genomes and identify specific genetic variations or markers has opened new avenues for understanding the genetic basis of health and disease. Genetic markers—specific DNA sequences linked to traits or diseases—are crucial for predicting disease risk, diagnosing genetic disorders, and developing personalized therapeutic strategies. This paper explores the significance of DNA sequencing and genetic markers, delving into their applications in medical research, diagnostics, and the potential for more individualized approaches to healthcare. By examining the current and future roles of genetic testing, we highlight how this technology is shaping modern medicine and improving patient outcomes
