Genomics is the study of the complete set of genes within an organism, known as its genome, and how these genes interact with each other and the environment. This field has revolutionized our understanding of biology, disease, and heredity, offering insights that range from evolutionary biology to personalized medicine. By sequencing and analyzing the DNA of various species—including humans—scientists can identify genetic variations that contribute to specific traits, diseases, or susceptibilities. Genomics is a multidisciplinary field that integrates techniques from bioinformatics, molecular biology, and genetics to better understand the function of genes in health and disease. Advances in genomics have led to groundbreaking therapies for genetic disorders, more effective and targeted medicines, and even the possibility of gene editing to eliminate or replace faulty genes. The ethical and social implications of these technologies are topics of ongoing debate.
