Background: Intellectual disability (ID) is an important medical and social problem that can be caused by different genetic and environmental factors. One such factor could be rDNA amplification and changes in rRNA expression and maturation. Aim of t

Cytogenetic Analysis of Seminemacheilus Lendlii (Hanko, 1925) (Teleostei: Nemacheilidae)

Autor: GAFFAROĞLU, Muhammet, Unal, Sevgi, Ayata, Muradiye Karasu

WOS: 000388312400018 The aim of this study is to reveal chromosomal properties of endemic Seminemacheilus lendlii fish species. Metaphase plates were obtained from kidney cells. The diploid chromosome number was observed 2n=50; consisting of eight pa

Short communication: Chromosome description and localization of nucleolus organizing regions (NORs) by Ag-staining technique in Alburnus filippii (Cyprinidae, Cypriniformes) in Anzali Lagoon, north Iran

Autor: Nazari, S., Pourkazemi, M., Porto, J.I.R.

Publikováno v: Iranian Fisheries Science Research Institute

The silver staining procedure is commonly used to visualize the activity of ribosomal RNA genes, since it has been established that only those NORs of metaphase chromosomes that are functionally active during the preceding interphase are capable of s

NOR Phenotype of Cyprinion macrostomus (Osteichthyes, Cyprinidae)

Autor: Yüksel, Eşref, Gaffaroğlu, Muhammet

In this study, nucleolus organizer regions of Cyprinion macrostomus were investigated. The diploid number of chromosomes of this species was 2n=50 consisting of three pairs of metacentric, 12 pairs of submetacentric, six pairs of subtelocentric and f
