I know nothing about muscle and even less about honeycombs, but I do know that 
nucleic acids (plasmids included) are measured in kilobase pairs (kb) whereas 
proteins are measured in kilodaltons (kD).  Plasmids are rather common in
fungi which  are eukaryotes, particularily in the mitochondria which are 
themselves believed to be prokaryotic in nature.
