sunlight contains ultraviolet radiations that have antimicrobial activity and effective against bacteria. ultraviolet radiations forms thymine or cytosine dimers in DNA or uracil dimers in RNA that cause inactivation or mutation in microbes which results in cell death. that is why sunlight can be a very good disinfectant for clothes and rugs or carpets.
