A mixture of fragmented DNA was electrophoresed in an agarose gel. After staning the gel with ethidum bromide, no DNA bands were observed. What could be the reason?

With respect to DNA fragmentation: Statement A: Gel electrophoresis and elution are two important processes. Statement B: After staining with ethidium bromide it has to be exposed to U.V. light.

How does one visualise DNA on agarose gel?

In agarose gel electrophoresis, DNA molecules are separated on the basis of their :

Fill in the blank During gel electrophoresis DNA fragments move to ........

Name the compound used to visualise them DNA fragments in gel electophoresis

A plasmid DNA and a linear DNA (both of the same size) have one site for a restriction endonuclease. When cut and separated on agarose gel electrophoresis, plasmid shows one DNA band while linear DNA shows two fragments. Explain.

Which of the given statement is correct in the context of observing DNA separated by agarose gel electrophoresis?

Choose the correct alternative. In gel electrophoresis, negatively/positively charged DNA fragments placed over cathode will move towards an electrical field.
