Horizontal gene transfer in Archaea
A. is infrequent in nature and therefore difficult to use for genetic studies in the laboratory.
B. has not been documented, thus all genetic studies of archaea are done via genomic sequencing.
C. frequently occurs in nature and has been used to perform genetic studies in the laboratory as well.
D. frequently occurs in nature, but there are very few laboratory studies because archaea do not cause human disease.
