Variant DNA sequences flanking the human insulin gene were found in the Danish population using restriction endonucleases (restriction fragment length polymorphism). The frequencies of these DNA sequences were determined in 47 non-insulin-dependent diabetics and 93 control individuals. We report an association between a restriction fragment length polymorphism of the insulin gene and NIDDM.

Genotypic variability among 96 Trichophyton rubrum strains which displayed different colony morphologies and were collected from four continents was investigated. Twelve markers representing 57 loci were analyzed by PCR fingerprinting, amplified fragment length polymorphism, and random amplified monomorphic DNA markers. Interestingly, none of the methods used revealed any DNA polymorphism, indi...

Placental Lactogen is a polypeptide hormone that is produced by the Placenta, also known as chorionic somatomammotropin hormone. It has both Growth Hormone and Prolactin activities on growth, lactation, and luteal steroid production. The objective of this study was to investigate the bovine Placental Lactogen (bPL) gene polymorphism of Holstein cows in Razavi Khorasan province. Blood samples we...

Biochemical polymorphism study is a method of determination of genetic variation. This variability could be a basis for selection and subsequent genetic improvement in farm animals. The polymorphism in the intron 1 of chicken growth hormone (cGH) gene was investigated in the Iranian native fowls by using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. The...

BackgroundIt has been confirmed that the connective tissue growth factor (CTGF) gene rs9402373 polymorphism is associated with fibrotic and inflammatory diseases. However, studies on relationship between polymorphisms in CTGF bowel disease (IBD) remain rare. Therefore, aim of this study was to assess association IBD susceptibility a Chinese population.Materials methodsTo establish an amplificat...

Banana micropropagation for obtaining free-virus plants frequently provokes somaclonal variation that could increase useful genetic variability in this asexually propagated crop. Both exploring the cycle of vitro culture which occurs and amount generated polymorphism, are necessary. In work, preliminary results during early cycles banana reported. Four randomly selected regenerated from fifth t...

InDel (insertion deletion length polymorphism) markers is designed for PCR detection based on the Insertion or of DNA fragments different sizes according to sequence a locus between individuals related species, which more and applied in crop genetic research due its rich polymorphism, operational simplicity reliability results. In this study, Qinyou 88 parents were analyzed through marker, four...

This article refers to viewing the role of molecular markers during analyzing genome plants and their importance in plant biotechnology. In recent years, we observed techniques programs for improving breeding preserving genetic resources has been observed, biochemical indicators which represent basic material through determining diversity between genotypes it is never affected by external surro...
