Deviations from the 'universal' genetic code.
Experimental data show that ciliates and mycoplasmas have genetic codes different from the 'universal' code. An evolutionary scheme which could explain the origin of terminators in a genetic code and relate it to the phenomenon of nuclear dimorphism in ciliates is proposed.
