Cytophotometric determinations of nuclear DNA content in tissues of the wax moth larva, Galleria mellonella Linnaeus

Creator:

Longo, Frank J., 1939-

Abstract:

The present study was undertaken to determine, by measurement of nuclear DNA, the degrees and frequencies of ploidy in the last larval instar of the moth Galleria mellonella Linnaeus. While such data have been amassed for a wide variety of vertebrate tissues, few studies have been concerned with invertebrates and...

Masters Thesis
The fine structure of spermatid differentiation in the mussel, Mytilus edulis, Linn

Creator:

Longo, Frank J., 1939-

Abstract:

The spermiogenesis of Mytilus edulis (a marine mussel) has been studied, employing techniques of light and electron microscopy and cytochemical preparations. The observations trace the development of the acrosomal complex, the nucleus, the mitochondrial middle-piece, and the flagellum. In early spermatids numerous membrane-bounded proacrosomal vesicles arise from several Golgi complexes...
