In “Synthesis”, replace “For each Genetic Engineer who Discovered a Codon which is currently present in the Genome, give that Genetic Engineer 1 Research.” (if it exists) with:-

For each Codon in the Genome, give 1 Research to each Genetic Engineer whose Mutation affected any of the Genome’s Nucleotides that form part of that Codon, during this action.

(If the proposal “Brushcutting” enacted, add the above quoted text as a new bullet point at the end of the list in “Synthesis”, instead.)

Remove the “Discoverer” column from the table in the rule Codons, and the text “and optionally the name of a Genetic Engineer (or idle Genetic Engineer) who Discovered them” from the same rule, if they exist.

Remove “The Genetic Engineers (if any) who most recently caused a Mutation in this Codon gain 3 Research Points each if they are in the Computer Room, 6 Research Points each if they are in any Room whose name starts with “Containment Cell” in which there is at least 1 Organism, and 0 Research Points otherwise..” from the ACT Codon in “Codons”.
