Note to players: Description acceptable. Floyd Romesberg was the first to create a UBP in order to formulate a system with this property. For 10 points each:
[10h] Name or describe this property imparted to xDNA via benzo-homologation. AEGIS, a system with this property, inspired a lab at Harvard led by Steve Benner to synthesize hachimoji DNA.
ANSWER: expanded DNA systems [accept Artificially Expanded Genetic Information System; accept descriptions of having more than four nucleotide bases; prompt on descriptions of including non-standard or synthetic nucleotide bases]
[10e] The hachimoji system includes isocytosine and 1-methylcytosine, or rS and dS, which form base pairs with a synthetic “iso” form of this nucleotide. That bond is analogous to cytosine’s base pairs with this nucleotide.
ANSWER: guanine [accept isoguanine; prompt on G; prompt on B]
[10m] Expanded DNA systems like hachimoji are being researched to understand possible methods of information storage for these organisms. Panspermia is a fringe theory that life originated with these organisms.
ANSWER: extraterrestrials [or aliens; prompt on microorganisms; prompt on ETs]
