How many genes to make a person? | Human World | EarthSky
We can think of all our genes together as the recipes in a cookbook for us. They’re written in the letters of the bases of DNA – abbreviated as ACGT. The genes provide instructions on how and when to assemble the proteins that you’re made of and that carry out all the functions of life within your body. A typical gene requires about 1000 letters. Together with the environment and experience, genes are responsible for what and who we are – so it’s interesting to know how many genes add up to a whole organism.
