Question

Quizplus · Accepted Answer

PCR can amplify small amounts of DNA and can specifically target a particular organism’s DNA for identification. It is also fast and does not require the bacterial growth of the organism, making it suitable for identifying slow-growing or non-curable bacteria. Southern blotting is a technique used for detecting specific DNA sequences and may be useful in identifying bacterial strains, but it is not as widely used as PCR. Replica plating is used to select for particular bacterial phenotypes and may not be useful for identifying individual bacterial species. Gas chromatography of fatty acids is used to determine the composition of bacterial cell membranes, which can help in identifying bacteria, but it requires a significant amount of bacterial growth and may not be suitable for identifying slow-growing or non-curable bacteria.
