I know that there have been many great discoveries made in the field of science. One that I like the best is the discovery of our DNA. I think that is the best and greatest discovery in Science, but that is only my opinion. I think this because thanks to that we know why we look like we do. This let's us know why we look how we do based on not only Physical appearances but also genetically  For example You may have brown hair, but you could have two different kinds of traits that make your hair look that way. You may have BB or Bb that means you will have brown hair because the B is dominant. It does not necessarily mean that you will have the same brown colored hair as any of your relatives because there are many different shades in colors and many different traits in your family.
      It also a great discovery because it helps us understand what is what gives us our look and how we are inside of our body. As you may know, the DNA is stored in your cells. Those cells are very important and that is what every organism is made up of. DNA now a days is very important and very well known that some scientists charge about 3 million dollars so that you can decide how your next child will be. They can now go into an egg and change the chromosomes so that you can create a very unique child. It is almost like picking what you want on your sandwich. I personally do not like that because I think that is best for nature to do what it wants and for God to decide that you be a mother or father of a child that was suppose to be created like that and not designed.Therefore,  DNA is the greatest scientific discovery, in my opinion.
