Quizplus · Accepted Answer

The polymerase chain reaction (PCR) is used to amplify a specific DNA sequence without the need for bacterial transformation. In PCR, small amounts of DNA can be copied millions of times, providing an ample supply for further analysis. Centrifugation is a technique used to separate components based on their size or density, while gel electrophoresis is a method of separating DNA fragments based on their size. Pepsin activation reaction is not a commonly used technique for gene manipulation.
