the aminosugar moiety of daunomycin , daunosamine , increases the binding of daunomycin to dna and also enhances chromosome banding. -- nogalamycin , which displays no differential quenching with the different dnas in solution , also fails to produce bands on chromosomes. -- these findings suggest that non-random nucleotide sequence arrangements along the chromosome are a basic determinant for dye interaction to produce the observed banding patterns .
