There are many ethical problems involved in cloning humans The technology to clone humans has not been explored Human reproduction is very different from that of other mammals Cloning humans would take too long.

Engage in “pure science” Cure all the diseases of the world Publish results in scientific journals Provide a product of service that is useful to society and results in earnings
53
Different cell lines (CHO & HeLa cells) are more suited to producing certain kinds of recombinant proteins. Prokaryotic cells specialize in certain tasks and can therefore grow more rapidly than eukaryotic cells. There is great cell variety in multicellular organisms in which different kinds of cells have different jobs to do. All of the above
