What is a genome?
Your body is made up of about one hundred, million, million cells (100,000,000,000,000). Each of these cells has a complete set of instructions about how to make your cells, their components and their components' components. This set of instructions is your genome.
Your genome is quite similar to everyone else's genome, which is why we all turn out to be human beings. But every other living thing also has a genome.
All living things have genomes. Beetles each have a beetle genome, which is a complete set of instructions for making a beetle. Cabbages have a cabbage genome and bacteria have a bacteria genome.
Extinct species, such as dinosaurs also had their own genomes.
