Site-directed mutagenesis allows researchers to produce a mutation at a ________ within a cloned DNA segment.
A) specific site
B) random site
C) semilocalized site that can later be identified by sequencing

Question

Quizplus · Accepted Answer

Site-directed mutagenesis allows researchers to intentionally introduce a mutation at a specific site within a cloned DNA segment. It is not a random process, and the mutated site can be identified and studied. Therefore, option A is the correct answer. Option B is incorrect because it suggests a random process, which is not the case for site-directed mutagenesis. Option C is also incorrect because the mutated site is intentionally chosen and identified, rather than being randomly localized and identified later by sequencing.
