Does anyone has idea as to WHY ACGT WORKS AS PER PHYSICS N NOT THE OTHER ARTIFICIAL ONES? LIKE SILICA BASED ONES?
You mean why DNA is carbon based rather than, say, silicone? If so, it's more a matter of chemistry than physics. Anyhoo - please make friends with Google - it can help you answer many questions, and asks for so little in return.

After the huge hint from exchemist I Googled what I guessed you were asking and received a good response I could post the link but not going to Again YOU ask Mr Google, absorb the information provided, come back to SciForum if Mr Google comes up short Please Register or Log in to view the hidden image!
I'm kind of curious what "other ones" the OP means. Is he referring to "other" nucleobases? Or other elements as a base for nucleobases? Are there "artificial silicon-based nucleobases"?
