A genome is the complete set of genetic material in an organism, including all of its genes and non-coding sequences of DNA or RNA in the case of some viruses. The genome contains all the information necessary for an organism’s growth, development, functioning, and reproduction, encoded within DNA (or RNA) sequences. In eukaryotes, the genome is contained within the cell nucleus, while prokaryotes have their genome in a single, circular DNA molecule. The human genome, for example, consists of approximately 3 billion base pairs of DNA arranged in 23 pairs of chromosomes, containing around 20,000-25,000 genes. Studying the genome helps scientists understand genetic diseases, evolutionary biology, and biological functions at a molecular level. Techniques such as DNA sequencing and genetic mapping are crucial in genomics, enabling the exploration of genetic variations and their implications on health and disease.
