Understanding Genomics: Unlocking the Blueprint of Life
Genomics, the study of an organism’s complete set of DNA, has emerged as one of the most transformative fields in modern biology. Unlike traditional genetics, which often focuses on individual genes, genomics examines the entirety of an organism’s genetic material—known as the genome. This holistic approach provides insights into how genes interact, how they contribute to traits, and how they influence health and disease.
At the core of genomics is the sequencing of DNA, which allows scientists to decode the precise order of nucleotides in the genome. Advances in sequencing technology over the past two decades have dramatically reduced the time and cost required to map a genome. This has enabled the study of complex organisms, from humans to plants, at an unprecedented scale. Sequencing not only reveals the genetic instructions encoded within DNA but also allows researchers to identify variations that may…
