Answer:
D) Beta galactosidase will not be produced.
Explanation:
Promoter is necessary to start the transcription of the structural gene. The position of promoter is important because the gene which is downstream to promoter will be transcribed and the gene upstream to the promoter will not be transcribed.
Lac operon has three structural gene lacZ, lacY, and lacA. Lac Z codes for β galactosidase, lac Z codes for permease and Lac A codes for transacetylase. So if promoter for the lac operon moves between the beta-galactosidase (lacz) gene and the permease (lacy) gene, then the beta-galactosidase gene will not be produced because it is places upstreamed to the promoter.

metalic
Explanation:
Atoms having a valence of electron of 1 or 2 are metals. They belong to the first and second group on the periodic table.
In metallic bonds, atoms of metals and alloys joins together.
- The formation of this type of bond is favored by the low ionization energy and a large number of electrons in the valence shells.
- The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
- Most physical properties of metals can be accounted for by this type of bonding.
