What is commonly done to view DNA fragments separated in a gel?

Answer and explanation

Correct answer: DNA bands are stained with a fluorescent dye

After gel electrophoresis, DNA fragments are stained with dyes such as ethidium bromide or SYBR Green. These dyes make the DNA bands visible under ultraviolet or blue light. Boiling, burying, or covering the DNA with paper does not reveal the bands. Exam tip: Each visible band represents DNA fragments of a particular size range.
