DNA Structure

Question 1

First to isolate DNA from pus soaked bandages; he named it “nuclein”

Answer 1

Friedrich Miescher

Question 2

Discovered that there are equal numbers of A and T bases in the DNA, and C and G bases, indicating that they are in pairs; base-pairing rule

Answer 2

Erwin Chargaff
