The Basics
Who is Gregor Mendel?
The scientist that first discovered that the number of guanine units is equal to the number of cytosine units, and the number of adenine units is equal to the number of thymine units.
The only scientist in the bunch who was not a man, was never given the correct amount of honor for her work, and used the technique of X-ray crystallography to first see DNA.
What are Adenine (A), Guanine (G), Thymine (T) and Cytosine(C); and A-T....G-C?
