Answer:
The staining solution used to see our banding patterns is ETHIDIUM BROMIDE.
Step-by-step explanation:
Ethidium bromide is a type of chemical that is used to visualize DNA band patterns in agarose gel electrophoresis. It binds to DNA and fluoresces when illuminated under UV light. Ethidium bromide is known as an intercalating agent. The structure of ethidium bromide enables it to be inserted between nitrogenous bases of the DNA molecule. This interaction is useful because when it is exposed to ultraviolet light, ethidium bromide fluoresces. Thus, the chemical provides means of tagging DNA molecules and visualizing them under UV light.
