PCR is used to?

• A. Translate DNA into proteins
• B. Cut DNA at specific sequences
• C. Amplify DNA
• D. Sequence DNA

Answer: (C)

PCR is a technique that amplifies a specific DNA sequence, meaning it makes many copies of that segment from a small starting amount. By cycling through temperatures, a DNA polymerase extends primers that flank the target region, producing exponential duplication of the chosen DNA. This amplification provides enough material for detection, cloning, or sequencing and is the reason PCR is so widely used in genetic analysis. The other activities described aren’t what PCR does: translating DNA into proteins is a cellular process called translation; cutting DNA at specific sites is done with restriction enzymes; and sequencing DNA involves determining the order of bases rather than creating multiple copies.
