書摘/試閱
The formation of G banding is closely related to the characteristics of Giemsa stain,which is a mixture of methylene blue,azure, and eosin. Bothmethylene and azure belong to the thiazine dyes and they bind to the phosphate groups in DNA and do not bind to proteins. As a result,chromosomestaining is determined by the binding of two thiazine molecules to DNA. On top of that,one molecule of eosin binds and forms the thiazineeosin complexat the ratio of 2: 1. Besides,staining is also enhanced by the hydrophobicenvironment which favors dye complex accumulation. Chromosomes rich in hydrophobic motifs facilitate the formation of the thiazineeosin complex. This indicates that proteins are important factors for G banding. In the repeated DNA sequences in chromosomes,the transcriptional activity is low,and packaging proteins are stable. Those proteins can form hydrophobicahelix motif with strong disulfide bonds, thus facilitate the accumulation of the dye complex, showing dark bands under the microscope.On the other hand,DNA regions encoding structural genes-have high transcriptional activity,and the packaging proteins are loosely bound.
