## **Core Concept**
The Polymerase Chain Reaction (PCR) is a laboratory technique used to amplify specific segments of DNA. This method is fundamental in molecular biology for various applications, including genetic testing, cloning, and forensic analysis. The invention of PCR revolutionized the field of genetics.

## **Why the Correct Answer is Right**
Kary Mullis is credited with inventing the PCR technique. He developed this method in the 1980s, which allows for the exponential amplification of DNA sequences. The process involves denaturation of DNA, annealing of primers to the target DNA sequences, and extension of the annealed primers by DNA synthesis enzymes. Mullis's invention significantly impacted molecular biology research and diagnostics.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Not provided due to lack of information on the specific options given.
- **Option B:** Not provided due to lack of information on the specific options given.
- **Option D:** Not provided due to lack of information on the specific options given.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that Kary Mullis was awarded the Nobel Prize in Chemistry in 1993 for his invention of PCR, along with Michael Smith, who developed site-directed mutagenesis. This technique has become a cornerstone in genetic engineering and diagnostics.

## **Correct Answer:** C. Kary Mullis
