In this study we examined, by denaturing gradient-gel electrophoresis and DNA sequence analysis , the possible presence of a codon 10 polymorphic site in normal oestrogen target organs and cells such as the uterus ( myometrium and endometrium ), in the placenta and peripheral blood mononuclear cells and in a benign uterus tumour ( leiomyoma ).
 ( DNA: DNA sequence, None) , ( DNA: codon 10 polymorphic site, None) , ( DNA: codon 10, None) , ( cell type: peripheral blood mononuclear cells, None)
