Addition to the mutant cell of an F factor carrying the wild type lac operon does not restore the ability of the cell to ferment lactose (i. e., the lac operon on the F does not confer ability to ferment lactose) Addition of cyclic AMP to the cells also does not restore the ability to ferment lactose. Given this information, which, if any, of the mutations listed above are still possible causes of the phenotype? Would the mutation(s) be cis-or trans-acting? Briefly explain your choice(s).

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.

explanation:

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
