The rising global demand for palm oil and its associated products has led to increased numbers of palm oil refineries with its attendant effluent discharge. Many researches have confirmed the ecological disruptive potentiality of Palm Oil Mill Effluent (POME), still further attention has to be directed at POME’s potential genotoxicity. The present study has made physico-chemical and genotoxicit...

background and aim: ring chromosomes are rare cytogenetic abnormalities that occur in less than 10% of hematopoietic malignancies. they are rare in blood disorder. the present review has focused on the ring chromosome associated with oncology malignancies. materials and methods: by reviewing the web-based search for all english scientific peer review articles published, was initiated using medl...

the diploid number among gekkonid lizards ranges from 2n=16 to 2n=46. the majority of geckos' chromosomes are small which makes the study of their chromosomes very difficult. for this reason, karyotype of cyrtopodion caspium and some similar gecko are still not known. the close relatives of c. caspium have variation in the chromosomal number in their populations. so to find out possible variabi...

The 45S and 5S rDNA loci were physically mapped by double-probe FISH on mitotic metaphase chromosomes in the six strains of F. esculentum tataricum. Results showed that tataricum very small similar. diploid karyotype formulas these two species 2n=2x=16=12m+4m (SAT) 2n=2x=16=12m+4sm (SAT), respectively. Four pairs IS, IIS, IIIL, VL, as well IL IVS esculentum, five VIIS, three IL, IVS, VIS There ...

Ciliates contain two kinds of nuclei: the germline micronucleus (MIC) and somatic macronucleus (MAC) in a single cell. The MAC usually have fragmented chromosomes. These chromosomes, capped with telomeres at both ends, could be gene size to several megabases length among different ciliate species. So far, no telomere-to-telomere assembly entire genome species has been finished. Development thir...

The laboratory mouse is recognized as the pre-eminent model for genetic research. Awareness of chromosomal patterns of experimental animals increases their value for a variety of different fields of study. We aimed to study mitotic chromosome preparations from NIH, C57BL/6 and Razi strains of mice, which are outbred, inbred and partially inbred laboratory mice respectively. Bone marrow cells we...
