**Core Concept**
DNA detection is a critical step in various molecular biology techniques, including PCR (Polymerase Chain Reaction), DNA sequencing, and forensic analysis. It involves identifying and quantifying the genetic material present in a sample. DNA detection methods often rely on specific enzymes, chemical reactions, or physical properties of DNA to amplify or visualize the target sequence.

**Why the Correct Answer is Right**
The correct answer involves the use of a fluorescent dye that intercalates between DNA base pairs, increasing the fluorescence emission when excited by a specific wavelength of light. This principle is utilized in real-time PCR (Polymerase Chain Reaction) to monitor the accumulation of amplified DNA products. The dye, typically SYBR Green or EvaGreen, binds to the minor groove of double-stranded DNA, allowing for the detection of the amplified DNA.

**Why Each Wrong Option is Incorrect**
* **Option A:** This is incorrect because it does not accurately describe a common method for DNA detection. While some techniques may involve the use of probes or primers, the description provided does not match a widely used DNA detection method.
* **Option B:** This is incorrect because it does not accurately describe a common method for DNA detection. While some techniques may involve the use of antibodies, the description provided does not match a widely used DNA detection method.
* **Option C:** This is incorrect because it does not accurately describe a common method for DNA detection. While some techniques may involve the use of electrophoresis, the description provided does not match a widely used DNA detection method.

**Clinical Pearl / High-Yield Fact**
When working with DNA detection methods, it's essential to remember that the choice of fluorescent dye or probe can significantly impact the sensitivity and specificity of the assay. Understanding the principles of DNA detection and the limitations of different methods is crucial for accurate results.

**Correct Answer: C. SYBR Green**
