The total genetic material of any organism [i.e., in humans, the 23 pairs of chromosomes that make up the genome, together with the genes they house, and a lot of DNA that does not contribute to genes (i.e., non-coding DNA)]. More specifically, it is the entire genetic complement of a prokaryote species and the haploid nuclear genetic complement of a eukaryotic species. Each animal or plant has its own unique genome. The originator of the term ‘genome’ was the botanist Hans Winkler (1877-1945) who derived it from combining ‘gene’ and ‘chromosome’ in 1920.
