The chromosomes of twenty individuals with normal karyotypes were studied to determine the patterns of staining with the Ag--AS technique. These patterns were shown to be variable from one individual to another, but characteristic and constant within each individual. In addition, one patient with ch

The length of 44 silver-stained human autosomal pachytene complements was shown to vary from about 300 micrometer to at least 535 micrometer. The lengths of the individual 22 autosomal chromosomes of eight complements representing this interval was measured and the relative lengths calculated. For m
A comparison of the sensitivity of silver and Giemsa N band staining for detection of the human nucleolar organizer regions (NORs) was carried out in cultured lymphocytes from three unrelated individuals. In sequentially stained cells examined from each subject, the mean number of Ag-NORs was greate
The absence of silver grain precipitation on human chromosome 17, consistently observed in four patients displaying the 17p variant, supports the hypothesis that the 17p variant is a structural heteromorphism rather than translocated satellite material.
The synaptonemal complex (SC), a part of the ultrastructure of the pachytene bivalent of eukaryotic organisms, is intimately connected with the pairing of homologous chromosomes. Its development, structure, and function have been studied extensively with the electron microscope during the past 20 ye
