Biology

6 0

Answer:

Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.

Ike is conducting a scientific experiment involving clear adhesive tape.
Nezavi [6.7K]

Answer:

see if the strips repel each other when brought close together

Explanation:

Electric fields can exert forces on objects, even if the objects involved are not touching. One way to demonstrate that electric fields exist around charged objects is to observe the effects of their forces at a distance.

Since Ike knows that each strip of tape carries a negative charge, he could see if the strips repel each other when brought close together.
