Alien biochemistry
#1
Hi everyone, I'm new to the forum here. I just signed up today, even though I've been reading orions arm for several years. One topic that raised my interest was about the nature of alien biochemistry. Specifically, about organisms that rely on carbon for structure, and water as a solvent. (These are called type 1 life forms in the OA page) Is it inevitable that carbon based life would use DNA and/or RNA to encode genetic information? Are other arrangements possible, or even likely?

A related question: Are there any type 1 biospheres in the OA universe that use something other than DNA? Or that maybe use DNA with different nucleotides, something other than A-G-C-T? I'm trying to learn more about this and am grateful for any answers.
