How many genes do you have?
Before the completion of the human genome project, many scientists were expecting to find 100,000 or more genes in our genome. This was based on the assumption that because we are one of the most complex creatures on Earth we should have lots of genes. However, it turned out we only have around 24,000 genes. This is a few more than a chimpanzee or a mouse, but nothing spectacular. Even more surprisingly, scientists discovered that large parts of our genome is made up of DNA that doesn’t code for genes.
