Genome Structure and Function: From Chromosomes ...
G1 progression is accompanied by a progressive straightening and unfolding of
chromonema fibers simultaneous with a decondensation of the fibers to yield
predominately -60-80 nm diameter chromonema fibers in middle G1. These
fibers ...
meres; and even none, if the chromomeres are not an accumulation of DNA but
chromonema whorls, which is not probable. Only one important difference is
visible: wherever spontaneous or experimental breaks of the chromosomes can
be ...
Richard Benedict Goldschmidt, 1958
Each chromosome can be longitudinally split into two chromatids, each
containing a highly coiled, fibre-like chromonema. The chromonema may be
composed of either a single or multiple strands of nucleoprotein material rich in
DN A and ...

Cell and Developmental Biology
Chromonema is the gene-bearing portion of chromosome, although each
chromonema may contain non-genic materials that serve to maintain its integrity.
The chromonema may be composed of 2, 4 or more fibrils depending upon the
species ...

Under these conditons, the contrast between the two organelles enables one to
see both of them clearly, even when the centromere lies adjacent to and
sometimes almost seems to be embedded in the chromonema, as in certain plant
...

The 20-nm fibers in such preparations are organized into a thicker unit, 100-200
nm in diameter. In stereoscopic photographs, this unit is seen to be helically
coiled and unquestionably represents the chromonema known from light
microscopy.
