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.
Best Answer: DNA is the entire genetic material. A Chromosome is a strand of DNA containging the genes. A gene is a part of a chromosome which carries the information that is passed on to offspring.NA forms chromosomes which in cells form genetic codes (genes) in the nucleus, DNA is copied in cell division to make new chromosomes and some (very few) mutate and form new genes.
