Adam B Shapiro

Chargaff did this in 1951. Here is one of his papers:

http://www.jbc.org/content/192/1/223.full.pdf+html?sid=7d29c101-7ca4-484e-9247-ec4daf328e9e

It might be possible to use NMR or MS techniques today to avoid having to hydrolyze the DNA.

Thank you very much for your reference, Adam B Shapiro. I wonder why these days, people are not doing the same thing ^^. And I am going to read that paper. Thank you ~
