[QUOTE="Old Man Jingles, post: 4143588, member: 18222"] While I agree with you, there are scientific theories that some family trees that do not have amino acids and proteins as their basic building blocks but rather XNA. So far, all known living things on Gaia have RNA and/or DNA as their basic building blocks and encoding instructions. Now I will ask you a question ... Do non-living molecules that contain RNA and DNA exist. [/QUOTE]
