Repetitive DNA sequences are a major component of eukaryotic genomes and may account
for up to 90% of the genome size. They can be divided into minisatellite, microsatellite and …

Satellite DNAs represent the most abundant fraction of repetitive sequences in genomes of
almost all eukaryotic species. Long arrays of satellite DNA monomers form densely packed …

Drosophila melanogaster plays an important role in molecular, genetic, and genomic studies
of heredity, development, metabolism, behavior, and human disease. The initial reference …

Background Centromeres are essential for chromosome segregation, yet their DNA
sequences evolve rapidly. In most animals and plants that have been studied, centromeres …

Chromosome segregation requires centromeres on every sister chromatid to correctly form
and attach the microtubule spindle during cell division. Even though centromeres are …

Centromeres are essential chromosomal regions that mediate kinetochore assembly and
spindle attachments during cell division. Despite their functional conservation, centromeres …

Heterochromatin in Drosophila has unusual genetic, cytological and molecular properties.
Highly repeated DNA sequences (satellites) are the principal component of …

We have investigated the mechanism that enables achiasmate chromosomes to segregate
from each other at meiosis I in D. melanogaster oocytes. Using novel cytological methods …

Heterochromatic regions of the eukaryotic genome harbour DNA sequences that are
repeated many times in tandem, collectively known as satellite DNAs. Different satellite …

Position–effect variegation (PEV) describes the stochastic transcriptional silencing of a gene
positioned adjacent to heterochromatin. Using FISH, we have tested whether variegated …
