Chromosomal organization of four classes of repetitive DNA sequences in killifish Orestias ascotanensis Parenti, 1984 (Cyprinodontiformes, Cyprinodontidae)
Orestias Valenciennes, 1839 is a genus of freshwater fish endemic to the South American Altiplano. Cytogenetic studies of these species have focused on conventional karyotyping. The aim of this study was to use classical and molecular cytogenetic methods to identify the constitutive heterochromatin distribution and chromosome organization of four classes of repetitive DNA sequences (histone H3 ...
متن کاملfocus on communication in iranian high school language classes: a study of the role of teaching materials in changing the focus onto communication in language classes
چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولDNA Fingerprinting Based on Repetitive Sequences of Iranian Indigenous Lactobacilli Species by (GTG)5- REP-PCR
Background and Objective: The use of lactobacilli as probiotics requires the application of accurate and reliable methods for the detection and identification of bacteria at the strain level. Repetitive sequence-based polymerase chain reaction (rep-PCR), a DNA fingerprinting technique, has been successfully used as a powerful molecular typing method to determine taxonomic and phylogenetic relat...
متن کاملChromosomal location polymorphism of major rDNA sites in two Mediterranean populations of the killifish Aphanius fasciatus (Pisces: Cyprinodontidae).
The chromosomes of the Mediterranean killifish, Aphanius fasciatus from two populations, the Lagoon of Venice (LV, 15 specimens) and the Lagoon "Stagnone di Marsala" (Sicily) (SM, 48 specimens), have been investigated using conventional Ag-staining and fluorescent in situ hybridization (FISH) with 18S rDNA probe. The two methods revealed variation in the number of major rDNA sites ranging from ...
متن کاملPotential Role of Phase Separation of Repetitive DNA in Chromosomal Organization
The basic principles of chromosomal organization in eukaryotic cells remain elusive. Current mainstream research efforts largely concentrate on searching for critical packaging proteins involved in organizing chromosomes. I have taken a different perspective, by considering the role of genomic information in chromatins. In particular, I put forward the concept that repetitive DNA elements are k...
