**Step-by-Step Solution:** 1. **Understanding the Nature of DNA**: DNA is a macromolecule that carries genetic information. It is composed of nucleotides and has a specific structure that makes it hydrophilic. 2. **Defining Hydrophilic**: The term "hydrophilic" refers to substances that have an affinity for water. These substances can dissolve in water and are often polar in nature. 3. **Cell Membrane Composition**: The cell membrane is primarily composed of a lipid bilayer, which is hydrophobic (water-repelling). This structure acts as a barrier to most hydrophilic molecules, including DNA. ...
