Summary:This paper deals with the staining of meiotic chromosomes of Helix aspersa spermatocytes and Allium jesdianum microsporocytes, according to Bernhard's method. The presence of positive staining was observed in zygotene axial cores, in the lateral elements of the synaptinemal complexes, and in the remains of these structures during diplotene. On the basis of present knowledge and the selectivity of this staining method as tested by ribonuclease it may be suggested that the positive-stained material represents an RNA-containing component. The relationship between this result and the general organization of the synaptinemal complex is discussed.
