two mutations of the lacI (repressor) gene have different effects. The IW mutation results in constant beta-galactosidase and permease production, even in the absence of lactose. The IS mutation prevents any production of these enzymes, even in the presence of lactose. Provide a possible explanation for the different effects of these two mutations on the repressor protein molecule

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
