I am sorry, but is this correct?
You're not saying that A can pair with any of A,T,C or G... and the same for the rest, are you?
I seem to recall [A]denosine pairing with [T]hymine only, and [G]uanine with [C]ytosine only - hence the double helical structure of DNA?
Please, correct me if I'm wrong... of course I'll check with my companion.

M*W: I did a lot of thinking and writing yesterday. I probably wasn't as clear as I should have been. It's okay by me to check with your friend. It's been awhile since I took the course in medical genetics. My work is mostly hands on.
