Select the method that detects target DNA in intact cells.

Question

Quizplus · Accepted Answer

Fluorescence in situ hybridization (FISH) is a method that uses fluorescent probes to bind to specific target DNA sequences within intact cells. This allows for the identification and visualization of specific DNA sequences within the context of the cell. PCR, Southern blot, and solution hybridization all require extraction of DNA from cells before detection can occur, and as a result, cannot be used to detect target DNA in intact cells.
