Interviewee: Erwin Chargaff. Erwin Chargaff talks about his name for Chargaff's ratios. (DNAi Location: Code > Finding the structure > Players > Erwin Chargaff > What Chargaff called the ratios)

Well you see the special thing is, there were the stupid name of the Chargaff Rules, I have never called them Chargaff Rules, but anyway that is the base pairing, I called it a complementary situation, I don't think I gave the name base pairing, I think that is one of the few things that Watson really did.

15495. Chargaff's ratios, 3D animation with narration

Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal. This parity is obvious in the final DNA structure.
