TLDR
A continuous 17‐kb alpha satellite fragment bordering the non‐satellite in human chromosome 21 is sequenced, which is devoid of higher‐order repeated structure, contains multiple rearrangements, and exhibits higher divergence of monomers towards the border, indicating the lack of efficient homogenization.About:

Journal ArticleDOI
Satellite DNAs between selfishness and functionality: structure, genomics and evolution of tandem repeats in centromeric (hetero)chromatin.
TL;DR: It is argued that tandem repeats may be advantageous forms of DNA sequences in (peri)centromeres due to concerted evolution, which maintains high intra-array and intrapopulation sequence homogeneity of satellite arrays, while allowing rapid changes in nucleotide sequence and/or composition of satellite repeats.
Journal ArticleDOI
Alpha-satellite DNA of primates: old and new families.
TL;DR: It is proposed that homogenization of AS may be limited to arrays participating in centromeric function, and after the establishment of the new arrays homogenized in the old arrays stopped.

Molecular structure and evolution of an alpha satellite/non-alpha satellite junction at 16p11.

TL;DR: Both phylogenetic and comparative analyses indicate that these pericentromeric-directed duplications occurred around the time of the divergence of the human, gorilla and chimpanzee lineages, resulting in the subtle restructuring of the primate genome among these species.
Journal ArticleDOI
Tandem repeats derived from centromeric retrotransposons
TL;DR: Analysis of monomers from two different CRM1TR loci shows that gene conversion is the major cause of sequence variation, which supports the conclusions from earlier studies that retrotransposons can give rise to tandem repeats in eukaryotic genomes.

Progressive proximal expansion of the primate X chromosome centromere
Mary G. Schueler,John M. Dunn,Christine P. Bird,Mark T. Ross,Luigi Viggiano,Mariano Rocchi,Huntington F. Willard,Eric D. Green +7 more
TL;DR: These studies demonstrate that the primate X centromere appears to have evolved through repeated expansion events occurring within the central, active region of centromeric DNA, with the newly added sequences then conferring centromer function.

Basic Local Alignment Search Tool
TL;DR: A new approach to rapid sequence comparison, basic local alignment search tool (BLAST), directly approximates alignments that optimize a measure of local similarity, the maximal segment pair (MSP) score.
Journal ArticleDOI
DNA sequencing with chain-terminating inhibitors
TL;DR: A new method for determining nucleotide sequences in DNA is described, which makes use of the 2',3'-dideoxy and arabinon nucleoside analogues of the normal deoxynucleoside triphosphates, which act as specific chain-terminating inhibitors of DNA polymerase.

The neighbor-joining method: a new method for reconstructing phylogenetic trees.
Naruya Saitou,Masatoshi Nei +1 more
TL;DR: The neighbor-joining method and Sattath and Tversky's method are shown to be generally better than the other methods for reconstructing phylogenetic trees from evolutionary distance data.
Journal ArticleDOI
Molecular drive: a cohesive mode of species evolution
TL;DR: There are circumstances in which the unusual concerted pattern of fixation permits the establishment of biological novelty and species discontinuities in a manner not predicted by the classical genetics of natural selection and genetic drift.
Journal ArticleDOI
Evolution of repeated DNA sequences by unequal crossover
TL;DR: Qualitatively, then, unequal crossover provides a reasonable and uncontrived explanation for the prevalence of highly repeated sequences in DNA and for the patterns of periodicity they evince.
