Answer:
Major cell parts function just like the structures and people who work together in a factory. Cells have strong cell walls and a cytoskeleton to keep their shape; the walls are made of fiber for protection just like a factory building has sturdy walls for support.
Since the DNA is damaged, the RNA created from it will not be correct. So after protein synthesis the protein will come out with a messed up shape. A change in the shape means a change of the function for a protein. So, In the end, the protein would not function as intended.
