Mutation
You are studying the genetic codes of three phenotypically identical E. coli bacteria: HB99, HB100 and HB101. While studying their DNA sequences, you note that a point mutation has in a the same gene in each of the E. coli strains. The gene encodes for an enzyme required to methylate lysine 27 on Histone 3: H3K27.
HB99 sequence: ATGCGTCACGTCGA
