Recent electron microscope studies of nuclei and chromosomes have shown that a
microfibril from 100 to 200 A thick is the basic morphological unit of chromosomes …

The higher order structure of chromosomes of Raji cells has been investigated with a field
emission type scanning electron microscope after the chromosomes had undergone surface …

An electron microscopic examination has been made of the testis of the cockroach after
fixation with glutaraldehyde. The tubular components of the spindle of cells in the first …

The early spermatid nuclei of the grasshopper, Acrida lata, have been observed electron
microscopically. The irregularly compact chromatin mass appears closely attached to the …

Publisher Summary The electron micrographs of the cell nucleus and chromosomes provide
at first sight a confusing and not very informative picture. The reasons for this are not …

The arrangement of the nucleosome-containing DNA fibers of chromosomes in mitotic HeLa
cells was studied by thin sectioning and electron microscopy. Thin sections of mitotic cells …

Prophase chromosomes in spermatocytes of the grasshopper, Melanoplus differentialis,
resemble the lampbrush chromosomes of amphibian oocytes in being long, thin and …

During the early to middle diplotene stages of meiotic prophase, the chromosomes in locust
spermatocytes contain a pair of dense fibrils, each about 250 Å thick, running parallel to the …
