Prophase chromosome unique band sequences: definition and utilization.
Extensive experience with the analysis of human prophase chromosomes and studies into the complexity of prophase banding patterns have suggested that at least some prophase chromosomal segments can be accurately identified and characterized independently of the morphology of the chromosome as a whole. The feasibility of identifying and analyzing specified prophase chromosome segments was thus investigated as an alternative approach to prophase chromosome analysis based on whole-chromosome recognition. Through the use of prophase idiograms at the 850-band stage (Francke, 1981) and a systematic comparison system, we have demonstrated that it is possible to divide the 24 human prophase idiograms into a set of 94 unique band sequences, each of which has a banding pattern that is recognizable and distinct from any other nonhomologous chromosome portion. The use of a unique band sequence approach in prophase chromosome analysis is expected to increase efficiency and sensitivity through more effective use of available banding information.
