Chromosome structural analysis : a practical approach /
The DNA of eukaryotes is packaged into chromosomes - each chromosome consisting of a very long molecule of DNA and various proteins (for example, histones), and the number of chromosomes being characteristic for the species concerned. Chromosome analysis can provide a great deal of information for m...
