Which of the following statement is correct in the context of observing DNA fragments separated by agarose gel electrophoresis?
1 Ethidium bromide stained DNA can be seen under exposure to UV light
2 DNA can be seen in visible light
3 DNA can be seen without staining in visible light
4 Ethidium bromide stained DNA can be seen in visible light
Explanation:
The separated DNA fragments can be visualised only after staining the DNA with a compound known as ethidium bromide followed by exposure to UV radiation (you cannot see pure DNA fragments in the visible light and without staining). You can see bright orange coloured bands of DNA in a ethidium bromide stained gel exposed to UV light

DNA fragments are
1 Negatively charged
2 Neutral
3 Either positively or negatively charged depending on their size
4 Positively charged
Explanation:
DNA fragments are negatively charged, therefore, when an electric current is applied to the gel in Agarose gel electrophoresis, DNA will migrate towards the positively charged electrode

Visualization of DNA on an agarose gel is achieved with the help of
1 Buffer
2 Ethidium chloride
3 Ethidium bromide
4 Sulphate in agarose
Explanation:
In gel electrophoresis, DNA fragments are separated are visualized with the stain called as Ethidium bromide.

After electrophoresis, the separated DNA fragment can be visualized in ethidium bromide gel exposed to UV light. These DNA fragments appear as ____ colored bands.
1 Blue
2 Orange
3 Green
4 Sliver
Explanation:
After electrophoresis, the separated DNA fragment can be visualized in ethidium bromide gel exposed to UV light. These DNA fragments appear as orange colored bands.
