Microorganism protect themselves against harmful UV light and visible light by using Iron minerals around themselves.
The iron minerals have unique properties in that they block damaging UV radiation while yet allowing organisms to utilise the portion of sunlight required for photosynthesis. UV rays kill cells by damaging their DNA. Two molecules of thymine, one of the bases that makes up DNA, react when exposed to light. The thymine dimer that results is extremely stable. The cell cannot perform its usual tasks if cellular processes are interfered as a result of an inadequate repair or unrepaired damage of thymine dimer.
