DNA samples are added into wells with the help of electric current.
<h3>How dna samples added to the wells?</h3>
DNA samples are added into wells at one end of a gel whereas an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
So we can conclude that DNA samples are added into wells with the help of electric current.
