167:15 >A building-block sequence is heteroserial if any blocks immediately adjacent >to it must be of a type different than any of those in the heteroserial >sequence. Examination of the genetic code of every prior rule and subsequent >"expensive laboratory experimentation by top men" has revealed GC, GCA, AG, >and CGA to all be heteroserial. Submitted by Mark Nau Judgement: INVALID. If I read this correctly, if "AG" is heteroserial this means that, whenever the sequence "AG" appears in a DNA sequence (as a sub-string), the building blocks immediately preceding and following it cannot be either "A" or "G". Unfortunately, rule 167:1 contains the text "and Guanidine are" which means that the genetic code for that rule contains the substring "AGA". Thus, AG cannot be heteroserial for all valid rules in this round. I cannot find any interpretation of this rule consistent with this fact. Style: Esoteric, but could have been interesting. Odd not to have analyzed the genetic codes more thoroughly... +0.5. -TWJ -- Rule Date: 2001-08-22 19:57:41 GMT
