Answer: A) they are eukaryotic cells Explanation: If you were to produce a protein in bacterial cloning systems, you would not get the same post transcriptional and post translational modifications because the prokaryotic and eukaryotic systems work differently on the modifications. Thus human recombinant protein genes are usually cloned in yeast cells. Also since they have a short generation time, they can be easily culture.
