The G-banded prophase chromosomes of man

Using a simple G-banding technique developed in our laboratory, analysis of late prophases enables the visualization of approximately 1000 bands in the haploid set of human chromosomes. These bands have been classified according to the recommendations of the Paris Conference. The increased resolution offered by this technique is likely to be useful in the study of the structure and molecular organization of chromosomes and in identifying minute chromosome defects in birth defects and neoplasia.
