In the most basic terms, genome is the genetic material of an organism. It is what tells the organism what to be and how to be. The genome is coded in DNA, or in RNA for many types of viruses. The term, genome, was coined in the 1920, as a portmanteau of gene and chromosome.
Gene and genome, both terms are associated with DNA and both terms are defined by using DNA molecule. DNA is the basic unit of heredity which is mainly found on chromosomes within the nucleus of cells or within other organelles. In general, an organism has one genome, but it has thousands of millions of genes in that particular organism.
