title: [Structural characteristics of DNA from sarcoma 45].
abstract: It is shown that thermodynamical parameters of thermal melting and the content of 5-methylcytosine for tumor DNA of sarcoma 45 differ from DNA in the norm. The reason of such difference is the presence of regions with changed DNA structure in sarcoma 45, which occurs apparently owing to hypermethylation of cytosine in tumor DNA.
