Cell and Developmental Biology
Two types of coils of chromonemal threads. chromatids are attached to each
other only by the centromere and become separated at the start of anaphase,
when sister chromatids migrate to opposite poles. Anaphase chromosomes thus
have ...

Fig. 9.2. Diagrammatic representation o( a paranemic and plectonemic coiling.

Chromosomes are made up of two chromatids. • Further, each chromatid is made
up of two chromonemal fibres. • Thus, each chromosome contains four
chromonemal fibres. • Each fibril contains a 20 to 40A DNA double helix
associated with ...

The chromonemal fibrils are coiled around each other in 2 different ways. There
are "paranemic" coils and "plectonemic" coils. The paranemic coils are loosely
coiled and threads easily separable while the plectonemic coils are interwound ...
The coils are of two types: Paranentic coils When the chromonemal fibrils are
easily separable from each other, such coils are called paranemic coils.
Plectonemic coils Here the chromonemal fibrils are closely intertwined and.
Nucleus 263.
These chromosomes are exceptionally broad, flattened and are characterised by
having large number of chromonemal strands in a single chromatid. In certain
dipteran larvae e.g. chironomus during certain developmental stages the straight

When the chromonemal fibrils are easily separable from each other, such coils
are called paranemic coils. 2. Plectonemic coils. Here the chromonemal fibrils
are closely interwined and they cannot be separated easily. Such coils are called

Thus, each chromosome contains four chromonemal fibres. • Each fibril contains
a 20 to 40A DNA double helix associated with protein. • 16 chromonemata are
found in mosquito prophase chromosomes. • In each chromatid 8 fibrils are found
...

Chromosome and cell genetics
This compaction is accomplished by (i) the 7 : 1 packing of DNA in nucleosome
fibre (interphase chromonemal filament), (ii) assembly (and contractive changes
of assembly) of axial segments within the axial domain of prophase chromatids, ...

Advances in chromosome and cell genetics
From terminological point of view it is important to stress the distinction that
chromonemal filament and chromonema (nucleosome fibre in molecular terms)
are used here to describe genetic linearity whereas chromatid is allotted to
variant ...
