the nucleotide sequence specificity of neocarzinostatin ( ncs ) , auromomycin ( aur ) , bleomycin ( blm ) , phleomycin ( phlm ) , and tallysomycin ( tlm ) has been determined by using these antibiotics and their associated chromophores to create strand scissions in end-labeled restriction fragments of dna and then determining the base sequence of the oligonucleotides formed .
