The ultrastructure of G- and C-banded chromosomes
Experimental Cell Research, 1975Abstract A method of visualizing chromosome bands by electron microscopy has been used to investigate the fine structural organization of G- and C-banded chromosomes. The following information has been obtained: 1. 1. G-bands, produced by trypsinization, were electron dense regions of highly packed chromatin fibres separated by regions in which ...

C-Band Heteromorphism in Breast Cancer Patients
Cancer Genetics and Cytogenetics, 1985The pattern of heteromorphism in the C-band-positive constitutive heterochromatin of human chromosomes #1, #9, and #16 was studied in peripheral lymphocytes of 54 breast cancer patients and 78 control individuals. The parameters of the heterochromatic regions analyzed were relative size, symmetry-asymmetry within homologous pairs, and prevalence of ...

The reaction to c-banding of c-banded constituents during mitotic cycle ofCrepis capillaris
The Botanical Magazine Tokyo, 1989The reaction to C-banding was investigated throughout the mitotic cycle ofCrepis capillaris (2n=6): (1) 18–22 C-bodies or C-bands were found during mid telophase and interphase to prophase and metaphase, and also 12–14 at late anaphase to early telophase in the mitotic cycle.

INHERITANCE OF Q AND C BAND POLYMORPHISMS
Canadian Journal of Genetics and Cytology, 1977Sequential Q and C banding of chromosomes from 36 individuals in three unrelated families revealed Q band variants on 6 different chromosomes and C band variants on 14 different chromosomes. These variants were inherited in Mendelian fashion with one exception in which a C band variant absent in the parents was found in a child. Although some of the Q

C-Banding of Plant Chromosomes
2016C-banding is used to differentially stain metaphase chromosomes in organisms having appreciable amounts of constitutive heterochromatin. Its primary benefits are that it is an inexpensive and a relatively fast method of identifying individual chromosomes and morphological or karyotypic variation, including large chromosomal rearrangements and ...

1980 International Electron Devices Meeting, 1980
The operating characteristics of a gyrotron travellng wave tube (gyro-TWT) operating at C-band are reported. Detailed testing showed that at higher beam voltage and current and with a magnetic field profile increasing in magnitude toward the rf output window, the output power could be increased from 50 kW at 16.6% efficiency to 128 kW at 24% efficiency.

10th International Conference on Digital Satellite Communications (ICDSC-10), 1995
The provision of a portable C-band terminal communicating with large hub stations through an 18 MHz band of INTELSAT V transponders is investigated. The considered multiple hub network with distributed control can support up to 18 2.4 kbit/s simultaneously active users equipped with 0.8 m antennas at remote sites.

Maize is one of the most important cereal crops to be extensively characterized cytologically. McClintock (1929) gave the first indication of heterochromatinous knobs within pachytene maize chromosomes. Proceeding from chromosome morphology and data on the location of knobs, she provided early identification of all maize chromosomes.
