Use of a drug selection eliminates those stem cells with nonhomologous recombination products. Viral vectors, microinjection, T-DNA, electroporation, and biolistic transfer. Used a nucleus from a terminally differentiated cell type. Created using constituitively expressed DNA from genetically unrelated species.

^^^ ANSWERS ARE IN PARENTHESES ^^^

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.
