Q:

Why are yeast cells frequently used as hosts for cloning?

A) they are eukaryotic cells B) they do not have plasmids
C) only yeast cells allow the gene to be cloned D) they easily form colonies
 
Answer & Explanation 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.
