The gel should be placed in the correct direction so that the DNA bands can move.
- DNA is negatively charged due to the presence of phosphate groups, so it can only move towards the positively charged anode, otherwise, it will not move.
- So, when gel electrophoresis is done the side of the gel where the wells have been created and DNA samples have been loaded is placed at the side of the cathode, whereas the other side is connected to the anode.
- When the current flows, the DNA fragments also move from negatively charged cathode to positively charged anode as per their mass and size.

Answer:

Answer:
Anti-inflammatory steroid treatments
Explanation:
The exaggerated or hyper active response of the immune system causes hyper sensitive reactions in the body. These immune reactions are generally uncomfortable and harmful for the body.
Type III hypersensitivity reaction mainly occur due to the neutrophils, IgG and complement. This hyper sensitivity reaction can be treated by anti-inflammatory steroid treatments as the neutrophils are the main mediators of this reaction.
Thus, the correct answer is option (1).
The answer for this should be D
