Dye-nucleoprotein Interactions in Giemsa Banding
Fixed chromosome preparations subjected to treatments such as pH 9 (I) or trypsin hydrolysis (2) and stained with Giemsa's demonstrate similar banding patterns irrespective of the pretreatments used. It has been shown that this phenomenon is the result of modifications of DNA-protein and protein-protein associations which alter dye interaction (3-5). It appears that only Giemsa's or related sta...
متن کاملFluorescence and Giemsa Banding Techniques
The C group chromosomes in man cannot be distinguished solely on morphological grounds, thus, the nature of an extra C chromosome remains unknown unless it is an X chromosome, which can be identified by its late DNA-replication pattern. Extra autosomes belonging to the C group have been observed with or without mosaicism in a wide variety of blood disorders (cf, de la Chapelle et al, 1970; Hell...
متن کاملGiemsa banding of chromosome 1gh+ and linkage analysis.
A four-generation transmission of 1qh+ chromosome was ascertained by routine chromosome analysis of a mildly dysmorphic and retarded 61/2-year-old female. Concordance between synophrys and the 1qh+ marker was the only consistent phenotypic relationship. The variant chromosome did not appear uncoiled, and Giemsa centromeric staining (C-bands) revealed an increased width of the heterochromatin co...
متن کاملGiemsa C-banding and the evolution of wheat.
The somatic chromosomes of common wheat, Triticum aestivum L. (2n = 6x = 42), and those of two of its diploid progenitors and T. speltoides, have been individually identified by a Giemsa staining technique. In wheat, telocentric chromosomes were used to aid the recognition of individual chromosomes, and an ideogram has been constructed depicting the C-band positions. There is no similarity in t...
متن کاملIdentification of Alfalfa Chromosomes Using Giemsa Banding and Image Analysis Techniques
Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Chromosomes of two diploid (2n=2x=16) subspecies of Medicago sativa, ssp. caerulea and ssp. falcata, their hybrid and tetraploid (2n=4x=32) cultivated alfalfa (M. sativa, ssp. sativa) were studied. Feulgen’s staining, Cand N-banding techniques and an image analysis system were used. The chromosomes of ssp. falcata hav...
