Stretching DNA to the limit

...u is drastically reduced in width with increasing exposure to UV light. UV light induces the crosslinking of the constituent DNA bases within the polynucleotide chains, as well as causes the formation of lesions by linking together the adjacent strands. The small changes in structure induced by this crosslinki...
