Pamphlets on Biology: Kofoid collection
H. J. Sax and K. Sax (1935) con- chide that the chromonemata of body-cell or
mitotic chromosomes are in the form of spirals at all periods of the chromosome
cycle and that this coiling prevents any intimate association of homologous ...

The Experimental Basis of Modern Biology
(i) Prophase The first indication of the chromosomes is the appearance of long,
very slender threads known as chromonemata. Each chromosome from the
moment of its first appearance can be seen to be double, the two chromonemata
being ...

In the matrix is present the chromonemata. The matrix is also formed of
achromatic or nongenic material. The presence of matrix is controversial but in
one organism, Luzula compestris (Woodrush), a plant belonging to the family
Juncaceae, ...
Dr. Sastry, Dr. Singh & Dr. Tomar, 2010
During prophase and sometimes during metaphase, the chromosomal material
becomes visible as very thin filaments called chromonemata. Several
chromonemata coiled together and enclosed in a separate common matrix form a
chromatid.

In trophoblast nuclei, bundles of chromonemata are visible, located under the
nuclear envelope and around the nucleolus. Sometimes, a band-like pattern can
be seen (Zybina, 1977). A characteristic of rodent trophoblast nuclei is the
variable ...

12.12. Structure of a chromosome and chromatids. (Vejdovsky, 1912). The
chromonemata form the gene-bearing portions of the chromosomes. The
chromonemata are embedded in the achromatic substance known as matrix (Fig.
