Why is restriction analysis done in competent host work?

Answer and explanation

Correct answer: To verify the presence and size of the insert in a recombinant plasmid

In restriction analysis, plasmid DNA is cut with specific restriction enzymes and the sizes of the resulting DNA fragments are examined. The expected band pattern confirms that the recombinant plasmid contains the correct insert and that its size is as expected. Option B refers to making cells competent, not to restriction analysis. Exam tip: after restriction digestion, compare the observed band sizes with the expected vector and insert fragments.
