Clinical manifestations of chromosome 19p13.11 duplication
Journal of Medical GeneticsBackground Chromosome 19 is the most gene-dense chromosome in the human genome, with a high frequency of segmental duplications that predispose it to genomic rearrangements. While deletions of chromosome 19 have been associated with various clinical conditions, duplications remain poorly characterised.

The mode of chromosome duplication in Crepis capillaris
Experimental Cell Research, 1958Abstract By the use of thymidine-H 3 , DNA of chromosomes in root cells of Crepis capillaris was labeled. At the first division following the incorporation of label all chromosomes were labeled. After one duplication in the absence of label these chromosomes produce one labeled daughter and one free of label.

THE EYE IN CHROMOSOME DUPLICATIONS AND DEFICIENCIES
Optometry and Vision Science, 1977The development of cytogenetic techniques over the past 20 years has produced a prodigious body of information about chromosomal abnormalities as they relate to ocular defects. Recognition of previously unappreciated syndromes and of chromosomal aberrations continues to occur with surprising frequency.

Chromosomal Duplication Syndromes: A Case Series
Neurology IndiaChromosomal deletion and duplication syndromes can lead to intellectual disability, autism, microcephaly, and poor growth. Usually manifestations of duplication syndromes are milder than that of the deletion syndromes. With the availability of tests for analysis of copy number variants, it is possible to identify the deletion and duplication syndromes ...

On the Increase of Sites for Chromosome Exchange Formation after Chromosome Duplication
Science, 1962Although radiation-induced chromosome exchanges are not distributed among cells according to a Poisson distribution, chromatid interchanges are. In Vicia faba the lack of fit to a Poisson distribution has been attributed to the occurrence of only two sites per cell where the chromosomes are close enough to form ...

The Time and Mode of Duplication of Chromosomes
The American Naturalist, 1957DNA synthesis is limited to interphase and frequently to a part of the interphase stage. When only a part of interphase is involved, DNA synthesis may occur at the beginning of interphase, near the middle of interphase or at the end, depending on the tissue and the species.

Duplication/deletion of chromosome 8p
American Journal of Medical Genetics, 1995The article by Guo et al. provides evidence for deletion of D8S596 loci (assigned to 8p23) in at least some patients with inverted duplications of 8p. Cytogenetic break points forming the inverted duplication are remarkably similar among most of their patients and those reported previously, suggesting a common mechanism for this interesting ...

Branched chromosomes as symmetrical duplications
Journal of Genetics, 19361. The bulb of theX-chromosome ofD. melanogaster and branched chromosomes in general are interpreted to be symmetrical duplications formed by a continuous unbranched chromonema.
