Polytene chromosomes in genetic research
Sedat & Manuelidis (1978*) have also published some modifications of methods
suitable for preparation of polytene chromosomes for different kinds of optical
analyses. Gruzdev & Reznik (1981*) have introduced a method for controlled ...

Color Atlas of Genetics
Polytene ("many threads") chromosomes, formed as a result of repeated DNA
synthesis without cell division, have a distinct pattern of chromosome banding
readily visible under the light microscope. These chromosomes, first observed in
cells ...

For Drosophila, contig maps come ready-made in the form of polytene
chromosomes. The Drosophila contig maps are aesthetically more pleasing than
DNA clone arrays. They also have a number of practical advantages. Each larva
has its ...

Molecular Biology of the Cell
creating a single giant polytene chromosome. The fact that some large insect
cells can undergo a direct polytene-to-polyploid conversion demonstrates that
these two chromosomal states are closely related and that the basic structure of a

Nuclear Cytology in Relation to Development
Polytene chromosomes of Diptera As seen in the preceding section, the polytene
chromosomes in the giant cells of Phaseolus are present in the diploid number (
the homologues are not paired). Unpaired polytene chromosomes, with a ...

In Situ Hybridization Protocols
(1), the technique of in situ hybridization to polytene chromosomes has played a
central role in the molecular genetic analysis of Drosophila melanogaster. The
power of in situ hybridization is due largely to the scale of polytene chromosomes

Anopheline Species Complexes in South and South-East Asia
Cytogenetic techniques Polytene chromosomes Anopheline females in the semi-
gravid stage have the best polytene chromosomes in ovarian nurse cells (Coluzzi
, 1968). Larvae at the IV instar stage have polytene chromosomes in salivary ...

Animal Cytology and Evolution
Studies with tritiated uridine have shown that all loci of these 'secondarily
polytene' chromosomes, and not merely those which are visibly puffed, are
actively synthesizing RNA. This is probably what we would expect, in view of the
presumed ...
