Main Points of the Paper
- High Frequency recombinant(Hfr) z+i+ x F-z-i-:
- within a few minutes of the time of entry of the z+i+ genes (which are closely linked) the synthesis of β-galactosidase commenced at maximal velocity in the absence of extracellular inducer
- inducible i+ allele appears dominant over the constitutive i- allele
- The authors of this paper eventually conclude that the repressor is not a protein, but evidence to refute this conclusion is shown here.
