Answer:
B) All DNA molecules will migrate up the gel toward the positive electrode.
Explanation:
Because the DNA has a negative charge - regardless the size-, all DNA molecules will migrate towards the positive electrode, at the top of the gel. This is due to the Coulomb's physic law "force of the interaction between the charges is attractive if the charges have opposite signs".
Instead of migrate down the gel , the DNA will do migrate up the gel (opposite direction).

can you upload the question again..coz some part are not showing
The cell is fundamental unit of structure and function in living organisms .All cells arise from pre-existing cells by division . The cell theory states that the cell is the basic unit of life and that all other cells are developed from an existing cell. This theory was developed way back in the mid of 17th century.
No, the vast majority of DNA mutations are not physically noticeable, and those that are noticeable physically are mainly cosmetic differences, such as a change in hair color, or heterochromia.
