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 …

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 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 …

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 …

Fine details of structure regarding the morphology of meiotic chromosomes at prophase
(tripartite groups, synaptinemal complexes) were studied. The most relevant findings are: 1) …

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 movement of chromosomes and the changes in spindle size have been recorded in
living spermatocytes of the grasshopper during the meiotic divisions. Anaphase movement …
