Question: What makes genetics so intriguing for you?

Christie Waddington answered on 17 Jun 2016:

The human genome is 2 million bases (letters) long. It is the code to make a human. Most of these letters don’t even code for anything, and yet they may still have a purpose. There are occasions when you change one letter, and you get a terrible genetic disease, which shows how perfect the DNA and the system to read the DNA has to be. Over millions of years of evolution, this system was developed to make us into what we are now. Its amazing how something like this can develop from single-celled organisms!
