Plasmolysis can be defined as the process where cells lose
water concentration in a hypertonic solution and this process leads to contraction or shrinkage of the pant cell
protoplasm. However, water leaves the cell due to hyperosmotic solution
because it contains solutes such as sorbitol, sucrose and mannitol.

Answer:
D. The two students who have two fragments have one restriction site in this region.
Explanation:
The DNA samples from the cheek cells were subjected to digestion with a restriction enzyme. This enzyme is an endonuclease and cuts the DNA at a specific sequence only. This sequence is called a restriction site. If the restriction site is not present in the sample DNA, the restriction enzyme cannot cut it. The presence of one restriction site in the sample DNA would cut it into two DNA fragments.
Similarly, the presence of two restriction sites in each DNA molecule would obtain a total of three DNA fragments per DNA molecule.
