- Abstract:
- ... Repetitive DNA, formerly referred to by the misnomer “junk DNA,” comprises a majority of the human genome. One class of this DNA, alpha satellite, comprises up to 10% of the genome. Alpha satellite is enriched at all human centromere regions and is competent for de novo centromere assembly. Because of the highly repetitive nature of alpha satellite, it has been difficult to achieve genome assembli ...

- Abstract:
- ... The W chromosome of most lepidopteran species represents the largest heterochromatin entity in the female genome. Although satellite DNA is a typical component of constitutive heterochromatin, there are only a few known satellite DNAs (satDNAs) located on the W chromosome in moths and butterflies. In this study, we isolated and characterized new satDNA (PiSAT1) from microdissected W chromosomes of ...

- Abstract:
- ... Satellite DNAs compose a large portion of all higher eukaryotic genomes. The turnover of these highly repetitive sequences is an important element in genome organization and evolution. However, information about the structure and dynamics of reptilian satellite DNA is still scarce. Two satellite DNA families, HindIII and TaqI, have been previously characterized in four species of the genus Iberola ...

- Abstract:
- ... Transposable elements (TEs) and satellite DNAs (satDNAs) are typically identified as major repetitive DNA components in eukaryotic genomes. TEs are DNA segments able to move throughout a genome while satDNAs are tandemly repeated sequences organized in long arrays. Both classes of repetitive sequences are extremely diverse, and many TEs and satDNAs exist within a genome. Although they differ in st ...

- Abstract:
- ... Constitutive heterochromatin is composed mainly of repetitive elements and represents the typical inert chromatin structure in eukaryotic cells. Approximately half of the mammalian genome is made of repeat sequences, such as satellite DNA, telomeric DNA, and transposable elements. As essential genes are not present in these regions, most of these repeat sequences were considered as junk DNA in the ...

- Abstract:
- ... Centromeres are defined by a specialized chromatin organization that includes nucleosomes that contain the centromeric histone variant centromere protein A (CENP-A) instead of canonical histone H3. Studies in various organisms have shown that centromeric chromatin (i.e., CENP-A chromatin or centrochromatin) exhibits plasticity, in that it can assemble on different types of DNA sequences. However, ...

- Abstract:
- ... Genomic studies rely on accurate chromosome assemblies to explore sequence-based models of cell biology, evolution and biomedical disease. However, even the extensively studied human genome has not yet reached a complete, ‘telomere-to-telomere’, chromosome assembly. The largest assembly gaps remain in centromeric regions and acrocentric short arms, sites known to contain megabase-sized arrays of t ...

- Abstract:

However, more recently, succeeding evidences have demonstrated that these sequences can indeed be transcribed, yielding satellite non-coding RNAs with important roles in the organization and regulation of g ...

These elements are mainly located at centromeres, pericentromeres, and telomeres and are major components of constitutive heterochromatin. Although originally satellite DNA was thought silent and inert, an increasing number of studies are providing evidence on its transcriptiona ...

- Abstract:
- ... Chromocenters are interphase nuclear landmark structures of constitutive heterochromatin. The tandem repeat (TR)-enriched parts of different chromosomes cluster together in chromocenters. There has been progress in recent years in determining the protein content of chromocenters, although it is not clear which DNA sequences underly constitutive heterochromatin apart from the TRs. The aim of the cu ...

- Abstract:
- ... Repetitive DNA—sequence motifs repeated hundreds or thousands of times in the genome—makes up the major proportion of all the nuclear DNA in most eukaryotic genomes. However, the significance of repetitive DNA in the genome is not completely understood, and it has been considered to have both structural and functional roles, or perhaps even no essential role. High-throughput DNA sequencing reveals ...

- Abstract:

However, centromere sequences, defining the chromosomal interface with spindle microtubules, remain largely absent from ongoing genomic studies and disconnected from functional, genome-wide analyses. This disparity results from the challenge of predicting the linear order of multi-megabase-sized reg ...

The general structure of DINEs includes two conserved blocks that may or not contain a region with tandem repeats in between. These central tandem repeats (CTRs) are similar within species but highly divergent between species. It has been assumed that CTRs ...

Mammalian artificial chromosomes (MACs) are non-integrating, autonomously replicating natural chromosome-based vectors that may carry a vast amount of genetic material, which in turn enable potentially prolonged, safe, and regulated therapeutic transgene expression and render MACs as attractive genetic vectors for “gene replacement” or for controlling differentiation pathways in target cells.
