list three key characteristics of DNA used in studying DNA in electrophoresis

Solution

Answer:

DNA is negatively charged due to sugar-phosphate backbone, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode.

Longer molecules migrate slowly compared to shorter DNA molecules because they experience more resistance within the gel.

The conformation of the DNA molecule can affect the movement of the DNA, In general the supercoiled DNA is more compact usually move faster than relaxed DNA.
