Question

Quizplus · Accepted Answer

Northern blotting is a technique used to measure gene expression by detecting the presence and quantity of a specific RNA in a complex mixture. It involves the separation of RNA by gel electrophoresis, transfer onto a membrane, and hybridization with a labeled probe that is complementary to the target RNA sequence. Therefore, option B is the correct choice. Option A, analyzing a specific region of DNA, is not possible with a northern blot, as it detects RNA rather than DNA. Options C and D involve different types of techniques, such as chromatin immunoprecipitation and enzyme-linked immunosorbent assay, respectively.
