Sex differentiation in goat fetus
Reproduction in domestic animals, as a major source of food and other products for human, has greatimportance and study of related subjects including sex differentiation and gonadogenesis during fetal life can solve many questions on normal development and various disorders of urogenital system. Since studies on sex differentiation in goat fetus are scarce, this study was performed. Twenty-five...

متن کاملEpigenetic aspects of differentiation.
A major challenge in biology is to understand how genetic information is interpreted to direct the formation of specialized tissues within a multicellular organism. During differentiation, changes in chromatin structure and nuclear organization establish heritable patterns of gene expression in response to signals. Epigenetic states can be broadly divided into three categories: euchromatin, con...
متن کاملsex determination of human fetus using nested-pcr
introduction: one of the goals of modern genetics is to develope safe prenatal diagnostic tests which do not constitute any risk to the fetus. one potentially non-invasive approach for doing so is to obtain fetal material from the maternal circulation. in this study we obtained rlaternal blood from the pregnant women and tried to determine sex of fetus by nested-pcr. material and methods: to de...
متن کاملDifferentiation of the subspecies of Campylobacter fetus by genomic sizing.
Campylobacter fetus subsp. fetus and C. fetus subsp. venerealis are currently differentiated by tolerance to glycine and by their epidemiology. Analysis of C. fetus DNA by pulsed-field gel electrophoresis, after digestion with the restriction endonucleases SmaI and SalI, was used to differentiate between the subspecies. All strains presently identified as C. fetus subsp. fetus had a genomic siz...
