Karyotype Analysis and Chromosome Banding
Nearly all methods of chromosome banding rely on harvesting chromosomes in mitosis. This is usually achieved by treating cells with tubulin inhibitors, such as colchicine or demecolcine (colcemid), that depolymerize the mitotic spindle and so arrest the cell at this stage. Excessively long incubations with Colcemid result in overcondensed chromosomes that band poorly and moreover some cell type...
متن کاملChromosome markers in Mus musculus: strain differences in C-banding.
The mitotic chromosomes of several inbred strains of mice and a series of F(1) hybrids have been analyzed by quinacrine staining and further characterized by the centromeric heterochromatin banding (C-banding). Inbred strains had the same amount of C-banding material on homologous chromosomes but showed variation in the amount on different chromosomes. F(1) hybrids showed characteristics of eac...
متن کاملC-banding karyotype and relationship of the dipodids Allactaga and Jaculus (Mammalia: Rodentia) in Egypt.
The C-banding karyotype of the jerboas Allactaga tetradactyla, Jaculus jaculus jaculus, and Jaculus orientalis was described and interspecific relationships were discussed. Despite the conservation of a relatively small amount of C-heterochromatin located at the centromeric region of some chromosomes in all karyotypes, a striking loss of C-heterochromatin was clearly observed in J. orientalis. ...
متن کاملThe reactions of the EcoRi and other restriction endonucleases.
The reaction of the EcoRI restriction endonuclease was studied with both the plasmid pMB9 and DNA from bacteriophage lambda as the substrates. With both circular and linear DNA molecules, the only reaction catalysed by the EcoRI restriction endonuclease was the hydrolysis of the phosphodiester bond within one strand of the recognition site on the DNA duplex. The cleavage of both strands of the ...
