Abstract
Moderate resolution thermal denaturation profiles are presented for the purified DNAs from Escherichia coli, cow, mouse, rat and chicken. All show multiple thermal transitions indicative of large blocks of DNA with very similar base composition. The eucaryotes all have much more of this kind of DNA than does E. coli. The satellite DNAs of cow and mouse are clearly visible and it is likely that the other transitions represent additional families of repeated DNA.
