Thinking back to the twisted ladder analogy, what do the sides of the ladder represent?

What are sugars and phosphates?

300
If one side of a strand of DNA reads ATCGA, use the base-pair rules to come up with the sequence on the other, complementary strand of the same DNA. (Complementary means matching)

Before anybody knew what the structure of DNA was, or even that bases paired up with each other, we only knew that there were sugars, phosphates, and the nitrogen bases A,G,C, and T in a DNA molecule. The name of the scientist who discovered that the % A equals the % T, and the % G equals the % C was? (Fact used to support the base-pair rules)

Who is Chargaff
