Telomeres are specialized sequences at the end of linear chromosomes. Its conserved structure and function among eukaryotic cells suggest important evolutionary functions. Telomere dynamics play major roles in chromosomal integrity, stability, cellular replication and aging, performing crucial genome protective functions.

Chromosomes distribute randomly to, but not within, human neutrophil nuclear lobes
Summary: The proximity pattern and radial distribution of chromosome territories within spherical nuclei are random and non-random, respectively. Whether this distribution pattern is conserved in the partitioned or lobed nuclei of polymorphonuclear cells

Small supernumerary marker chromosomes derived from human chromosome 11
Introduction: With only 39 reported cases in the literature, carriers of a small supernumerary marker chromosome (sSMC) derived from chromosome 11 represent an extremely rare cytogenomic condition.Methods: Herein, we present a review of reported sSMC(11),

Differences in the localization and morphology of chromosomes in the human nucleus [PDF]
Using fluorescence in situ hybridization we show striking differences in nuclear position, chromosome morphology, and interactions with nuclear substructure for human chromosomes 18 and 19.

Scanning conductance microscopy investigations on fixed human chromosomes
Scanning conductance microscopy investigations were carried out in air on human chromosomes fixed on pre-fabricated SiO2 surfaces with a backgate. The point of the investigation was to estimate the dielectric constant of fixed human chromosomes in order ...

Three-dimensional maps of all chromosomes in human male fibroblast nuclei and prometaphase rosettes [PDF]
Studies of higher-order chromatin arrangements are an essential part of ongoing attempts to explore changes in epigenome structure and their functional implications during development and cell differentiation.

Staining and Embedding of Human Chromosomes for 3-D Serial Block-Face Scanning Electron Microscopy
The high-order structure of human chromosomes is an important biological question that is still under investigation. Studies have been done on imaging human mitotic chromosomes using mostly 2-D microscopy methods.

Painting of human chromosomes with probes generated from hybrid cell lines by PCR with Alu and L1 primers [PDF]
Specific amplification of human sequences of up to several kb length has recently been accomplished in man-hamster and man-mouse somatic hybrid cell DNA by IRS-PCR (interspersed repetitive sequence — polymerase chain reaction).

Sorting of chromosomes by magnetic separation [PDF]
Chromosomes were isolated from Chinese hamster x human hybrid cell lines containing four and nine human chromosomes. Human genomic DNA was biotinylated by nick translation and used to label the human chromosomes by in situ hybridization in suspension ...

Specific staining of human chromosomes in Chinese hamster x man hybrid cell lines demonstrates interphase chromosome territories [PDF]
In spite of Carl Rabl's (1885) and Theodor Boveri's (1909) early hypothesis that chromosomes occupy discrete territories or domains within the interphase nucleus, evidence in favor pf this hypothesis has been limited and indirect so far in higher plants ...
