Comparison of chromosomal ideograms and “G-banded” human chromosomes Note: “Giemsa” banding is name for the German microbiologist Gustov Giemsa who developed a stain containing methylene blue, eosin and azure B for staining tissues and microorganisms (1904). Giemsa stain binds more strongly to AT-rich DNA compared to GC-rich DNA
