The DNA fragments separated on an agarose gel can be visualized after staining with:
1. Acetocarmine
2. Aniline blue
3. Ethidium bromide
4. Bromophenol blue
DNA fragments are:
1. Negatively charged
2. Neutral
3. Either positively charged depending on their size
4. Positively charged
What is the criterion for the movement of DNA fragments on agarose gel during gel electrophoresis?
1. | The smaller the fragment size, the farther it moves |
2. | Positively charged fragments move to farther end |
3. | Negatively charged fragments do not move |
4. | The larger the fragment size, the farther it moves |
