What is a genome and what is genomics?

A genome is the complete set of genetic material (DNA) in an organism, including all genes and non-coding sequences. Genomics is the study of genomes, including their structure, function, evolution, and mapping. Key areas include: structural genomics (physical organization and mapping), functional genomics (gene function through expression studies), comparative genomics (comparing genomes across species), and personal genomics (individual genetic variation). Technologies like next-generation sequencing have enabled rapid genome sequencing and analysis, revolutionizing our understanding of biology and enabling personalized medicine.
