Three-dimensional arrangements of chromatin and chromosomes: old concepts and new techniques.
The studies of early cytologists, well before the turn of this century, indicated that the positions of mitotic chromosomes in a particular metaphase cell correlated with their respective positions in preceding cell divisions. Observations of this type led to the concept that metaphase chromosomes were not simply aggregations of dispersed chromatin. Furthermore, when it became clear that chromo...
متن کاملThe replicon revisited: an old model learns new tricks in metazoan chromosomes.
The origins of DNA replication were proposed in the replicon model to be specified genetically by replicator elements that coordinate the initiation of DNA synthesis with gene expression and cell growth. Recent studies have identified DNA sequences in mammalian cells that fulfil the genetic criteria for replicators and are beginning to uncover the sequence requirements for the initiation of DNA...
متن کاملNew Insights into Phasmatodea Chromosomes
Currently, approximately 3000 species of stick insects are known; however, chromosome numbers, which range between 21 and 88, are known for only a few of these insects. Also, centromere banding staining (C-banding) patterns were described for fewer than 10 species, and fluorescence in situ hybridization (FISH) was applied exclusively in two Leptynia species. Interestingly, 10-25% of stick insec...
