  1. Molecular cytogenetics

    Molecular cytogenetics involves the combination of molecular biology and cytogenetics . In general this involves the use of a series of techniques referred to as fluorescence in situ hybridization , or FISH, in which DNA probes are labeled with different colored fluorescent tags to visualize one or more specific regions of the genome. FISH can either be performed as a direct approach to metaphase chromosomes or interphase nuclei. Alternatively, an indirect approach can be taken in which the entire genome can be assessed for copy number changes using virtual karyotyping. Virtual Karyotype Virtual karyotypes are generated from arrays made of thousands to millions of probes, and computational tools are used to recreate the genome in silico .

  1. Dicentric chromosome

    Unreferenced stub auto yes date December 2009 Dicentric chromosome is an aberrant chromosome having two centromere s. Dicentric chromosomes form when two chromosome segments from different chromosomes or from the two chromatids of a single one , each with a centromere, fuse end to end, with loss of their acentric fragments. Dicentrics, despite their two centromeres, may be mitotically stable if one of the two centromeres is inactivated, or if the two centromeres always coordinate their movement to one or the other pole during anaphase. Such chromosomes are formally called pseudodicentric. The most common pseudodicentrics involve the sex chromosomes or the acrocentric chromosomes Robertsonian translocation . Evaluation of centromere function by Fluorescent in situ hybridization FISH combined with immunofluorescence analysis of centromere and kinetochore proteins is a specialized procedure in some clinical cytogenetics laboratories.

G banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosome s.It is useful for identifying various genetic diseases through the photographic representation of the entire chromosome complement. ref name Speicher Speicher, Michael R. and Nigel P. Carter. The New Cytogenetics Blurring the Boundaries with Molecular Biology. Nature Reviews Genetics, Vol 6.

Dark bands that take up the stain are strongly A,T rich gene poor . The reverse of G bands is obtained in R banding. Banding can be used to identify chromosomal abnormalities, such as Chromosomal translocation translocation s, because there is a unique pattern of light and dark bands for each chromosome. ref name Speicher It is difficult to identify and group chromosomes based on simple staining because the uniform color of the structures makes it difficult to differentiate between the different chromosomes. Therefore, techniques like G banding were developed that made bands appear on the chromosomes. These bands were the same in appearance on the homologous chromosomes, thus, identification became easier and more accurate. The acid saline giemsa protocol reveals G bands.

The species is distributed throughout much of southern Iran , particularly in the Zagros mountains. It is also known as the Iranian Mouse like Hamster , though there are several species of mouse like hamster found in different parts of Iran. This is the largest species of mouse like hamster. They are dark grey on top and white underneath. They are found in habitat ranging from barren rocky hillsides to wetter regions. They are known to feed on herbs and grass seed. Graphodatsky et al. 2000 recovered three distinct karyotype s from different regions throughout the range of C. bailwardi 2n 37, FNa 44 2n 52, FNa 56 2n 50, FNa 50 . This may suggest that further taxonomic revision is required. Vorontsov et al. 1979 emphasized how little is known about the species and that the current definition is based largely on distribution. Many sources still refer to all members of Calomyscus as part of the species Calomyscus bailwardi .
