Morphological Analysis of Transcription in Insect Embryosinsects because it is at these stages that transcriptional induction generally occurs. This review focuses on an examination of the above issues based on morphological analyses of transcription in the fruit fly, ., and in the milkweed bug, ..

Morphological Manifestations of Ribosomal DNA Amplification during Insect Oogenesisgenesis provide the protein synthetic machinery of early embryogenesis. In such organisms, large amounts of ribosomal RNA are synthesized and accumulated during oogenesis (Harris and Forrest, 1967). In order to accomplish this, the oocytes may amplify the genes coding for ribosomal RNA (see Gall, 1969, and Tobler, 1975, for reviews).

The Cytoplasmic Architecture of the Insect Egg Cells remains largely unknown with respect to ultrastructure. This may mainly be due to technical reasons: the prevalence of yolk and the extremely resistant egg covers of insect eggs provide considerable handicaps for fixation and sectioning. Descriptions of the egg shell are therefore much more frequent than publications dealing with the egg cell.
