There are certain fungi that use melanin to trap energy from ionising radiation. They grow in the ruins of Chernobyl.

but I've seen no theories on how to make the sugar part of DNA or RNA. It's a huge open question.

See the current issue of Scientific American (September 2009, pp.38-45), where John Sutherland's*" work on synthesis of RNA via 2-aminooxazole is discussed. This route bypasses the synthesis of sugar.

(** John Sutherland et al., University of Manchester, UK, if anyone wants to try to find the paper(s) direct.)

EDIT: Spelling of "2-aminooxazole"
