Genomie, or genomics in English, is the branch of biology that studies genomes—the complete set of genetic material present in an organism or cell. It encompasses the structure, function, evolution, and mapping of genes and noncoding regions, as well as the organization and regulation of the genome. Genomics integrates experimental biology with computational analysis to interpret the sequences and variations that comprise genomes.

Key methods include high-throughput DNA sequencing, genome assembly and annotation, and comparative genomics. Bioinformatics tools analyze genetic variation, gene function, regulatory elements, and evolutionary relationships across species. Plan of data: reference genomes, variant catalogs, and functional maps.

Applications include human health through personalized medicine and cancer genomics, agricultural breeding and biotechnology, and ecological and evolutionary research. Genomics underpins projects to understand life’s diversity and to monitor pathogens, track outbreaks, and improve crops.

History and ethics: Genomics emerged from the sequencing of model organisms and the Human Genome Project in the late 20th century. It emphasizes open data and collaboration, but raises privacy and consent concerns for genomic information, as well as issues of data sharing, ownership, and potential discrimination.

Challenges and future directions: Interpreting the clinical significance of genetic variants remains a major hurdle. Integration with transcriptomics, proteomics, and phenotypic data requires robust standards and infrastructure. Ongoing advances promise precision medicine, synthetic biology, and deeper insight into evolution and development.
