Textbook Question
Chapter 17, Problem 5U
In terms of studying gene function, what is the main benefit that genome editing has over RNAi?
a. Genome editing can eliminate gene function; RNAi simply reduces the levels of gene products.
b. Genome editing does not require that recombinant DNA be produced, whereas RNAi always does.
c. Genome editing always works, but RNAi rarely works.
d. Genome editing is done in bacteria, which are easier to manipulate than the eukaryotic cells in which RNAi is done.
