8. In what way did gene therapy, the replacement of a faulty gene with a normal one, stimulate medical research? (what did we need to know to be successful with gene therapy?)
(5 Points)
New medications had to be developed and tested.
The effects of viral DNA had to be studied.
The way in which DNA replicates had to be determined.
O The genes on each chromosome had to be mapped and described.

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.
