The correct response is:
**A DNA binding stain causes the DNA fragments to be visible.**
In gel electrophoresis, the DNA fragments are separated based on size as they move through the gel when an electrical current is applied. However, the fragments themselves are not visible until a DNA binding stain (such as ethidium bromide or SYBR Green) is used, which binds to the DNA and fluoresces under UV light, allowing the distinct "banding" pattern to be seen.
