Polymorphism of Human Constitutive Heterochromatin [PDF]
Science, 1971 Genetic polymorphism has been demonstrated in man for many characteristics including blood groups, serum proteins, tissue enzymes, and hemoglobins. A class of chromosomal polymorphism involving constitutive heterochromatin has now been found. Through the use of a special technique that permits visualization of heterochromatin, seven heterochromatin ...

Constitutive heterochromatin: a surprising variety of expressed sequences [PDF]
Chromosoma, 2009 The organization of chromosomes into euchromatin and heterochromatin is amongst the most important and enigmatic aspects of genome evolution. Constitutive heterochromatin is a basic yet still poorly understood component of eukaryotic chromosomes, and its molecular characterization by means of standard genomic approaches is intrinsically difficult ...

Distribution of constitutive heterochromatin in carnivores
Cytogenetic and Genome Research, 1977The distribution of constitutive heterochromatin (C-banding) in the genomes of nine species of Felidae, one species of Mustelidae, two species of Procyonidae, one species of Viverridae, one species of Canidae, and one species of Ursidae has been studied. In the chromosomes of several felid species the C-band is apparently absent. A few chromosomes show

The constitutive heterochromatin of porcine chromosomes
Journal of Heredity, 1982The constitutive heterochromatin of porcine chromosomes was cytologically resolved into four types by using a combination of both C-banding techniques and base specific DNA binding fluorochromes. The four types of constitutive heterochromatin are: 1) C-band positive, A-T rich heterochromatin located in the centromeric region of acrocentric chromosomes;

Cytological differentiation of constitutive heterochromatin
Chromosoma, 1974The constitutive heterochromatin, as demonstrated by the C band technique, may be subdivided into a number of categories when other characteristics are considered. The responses to fluorochromes QM and 33258 Hoechst, the behavior following G band staining, the repetitive DNA content, and many other criteria are useful for the classification of ...

Lateral asymmetry in human constitutive heterochromatin
Chromosoma, 1975Human lymphocytes were grown for one replication cycle in BrdU, stained with 33258 Hoechst, exposed to UV light and subsequently treated with 2 x SSC and stained with Giemsa. This technique differentially stains the constitutive heterochromatin of chromosomes 1, 9, 15, 16, and the Y. In the heterochromatin of chromosome 9 both sister chromatids stained

Characterization of human chromosomal constitutive heterochromatin
Canadian Journal of Genetics and Cytology, 1986The constitutive heterochromatin of human chromosomes is evaluated by various selective staining techniques, i.e., CBG, G-11, distamycin A plus 4,6-diamidino-2-phenylindole-2-HCl (DA/DAPI), the fluorochrome D287/170, and Giemsa staining following the treatments with restriction endonucleases AluI and HaeIII.

Satellite DNA in Constitutive Heterochromatin of the Guinea Pig [PDF]
Science, 1970 Total DNA and DNA from the heterochromatin and euchromatin fractions of male guinea pig liver nuclei were analyzed by cesium sulfate-silver density-gradient centrifugation. Total DNA is composed of three components: a heavy satellite DNA, a main DNA of intermediate density, and a light satellite DNA.
