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

✦ Synopsis
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 most of the chromosomes a 1:1 relationship was found between the relative length and the corresponding relative DNA content (Mendelsohn et al. 1973). For some of the chromosomes this ratio seemed to deviate systematically from the 1:1 ratio. The data indicate a different organization of certain stages of the meiotic and the mitotic chromosome (Bak et al. 1979).

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 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.
A combination of the silver-staining method of the nucleolus organizer regions (NORs) with a Giemsa-banding method is described. This double staining allows a rapid identification of the NOR-bearing chromosomes.
The Ag stainability of the nucleolus organizer region (NOR) was studied in the acrocentric chromosomes identified by Q banding of cultured lymphocytes in 41 karyotypically normal persons (33 males and 8 females) originating from southeast Estonia. The data obtained are compared with those establishe
