For example, in the human genome, we have over 3 billion nucleotides, and that's many, many, many nucleotides. You can imagine trying to write down all the billions of nucleotides on paper if we didn't actually have computers. But because we have computers, we have a very quick and a very efficient way of storing and accessing all the data that we collect over the years. And so, for example, if we find that particular DNA molecule at the crime scene, we can then use the computer to essentially match it up with the DNA in that particular individual. And this gives us a very quick and effective way to basically finding who committed that crime. And computers are used in a variety of different ways.
