Within the last 20 years, scientists and doctors Within the last 20 years, scientists and doctors have learned about the ‘code’ that we call have learned about the ‘code’ that we call DNA. This code is made up of Adenine, DNA. This code is made up of Adenine, Thymine, Cytosine, and Guanine (the A’s, T’s, Thymine, Cytosine, and Guanine (the A’s, T’s, C’s, and G’s) we’ve looked at in our textbook C’s, and G’s) we’ve looked at in our textbook on page 67.on page 67.
