Short Answer: The ozone layer protects the DNA of all surface dwelling life, by absorbing UltraViolet-B from our Sun.
More detail
The ozone layer is the product of very short wave Ultraviolet light (UV-B) breaking apart oxygen molecules. When ozone is formed, it serves to block energetic UV (UV-B) that other molecules don't, and acts to moderate day / night temperature swings a little bit.
Ozone absorbs UV-B, which would otherwise damage our DNA, and the DNA of all surface dwellers on Earth (including phytoplankton in the oceans). This absorption of UV-B or more energetic light breaks the ozone down into an oxygen molecule and a single oxygen atom. A few of these fragments reassemble as ozone. But primarily UV-B is required to break apart more oxygen to make replacement ozone.
The ozone layer is like a blanket that shields Earth (not just the living things). It is a "greenhouse gas" that moderates day / night temperature swings, and allows the "heat" of the nitrogen and oxygen at altitude to be radiated away (both up and down).
