A polycephalic larva of Taeniidae family isolated from abdominal cavity of a great gerbil (Rhombomys opimus) from Golestan province, northern Iran, was subjected to molecular analysis. Genomic DNA from the larva was obtained using a DNA extraction tissue kit. Polymerase chain reaction was performed for amplification of the partial 12S rRNA, cytochrome c oxidase subunit 1 (cox1...

Genetic variation and inheritance of randomly amplified polymorphic DNA (RAPD) markers in female grass carp (Ctenopharyngodon idella) and male bighead carp (Hypophthalmichthys nobilis) and their F1 offspring hybrid have been studied. For this purpose, genomic DNA was extracted from muscle tissue according to phenol-chloroform method, and six decamer primers were used for amplifying polymorphic ...

BACKGROUND Studies in cell culture and animal models indicate that arsenic exposure induces modifications in DNA methylation, including genome-wide DNA hypomethylation. It is not known whether arsenic exposure influences genomic DNA methylation in human populations chronically exposed to arsenic-contaminated drinking water. OBJECTIVE The objective of this study was to determine whether arseni...

The gDNA isolated from Cyclina sinensis from Gochang (GOCHANG), Incheon (INCHEON) and a Chinese site (CHINESE), were amplified by PCR. Here, the seven oligonucleotide decamer primers (BION-66, BION-68, BION-72, BION-73, BION-74, BION-76, and BION-80) were used to generate the unique shared loci to each population and shared loci by the three cyclina clam populations. As regards multiple compari...

G-rich regions have the potential to form G4 DNA upon replication, which can lead to genomic instability. FANCJ, a G4 DNA helicase, has been shown to be critical for the stability of regions that match the G4 signature motif by experiments analyzing its nematode homolog.

In order to maintain genome integrity, it is essential that any DNA damage is repaired. This is achieved in diverse ways in all cells to ensure cellular survival. There is a large repertoire of proteins that remove and repair DNA damage. However, sometimes these processes do not function correctly, leading to genome instability. Studies of DNA repair and genome instability and their causes and ...

BACKGROUND High-resolution melting curve analysis is an accurate method for mutation detection in genomic DNA. Few studies have compared the performance of high-resolution DNA melting curve analysis (HRM) in genomic and whole-genome amplified (WGA) DNA. METHODS In 39 paired genomic and WGA samples, 23 amplicons from 9 genes were PCR amplified and analyzed by high-resolution melting curve anal...
