Spectral Representations of Alpha Satellite DNA
نویسنده
چکیده
Detection of tandem repeats can be used for phylogenic studies and disease diagnosis. The numerical representation of genomic signals is very important, as many of the methods for detecting repeated sequences are part of the DSP field. These methods involve the application of a kind of transformation. Applying a transform technique requires mapping the symbolic domain into the numeric domain in such a way that no additional structure is placed on the symbolic sequence beyond that inherent to it. Here we investigate the application of spectral analysis and spectrograms using a novel numerical representation to identify and study alpha satellite higher order repeats in human chromosomes 7 and 17. Key-Words: Sequence Repeats, DNA Representations, Alpha Satellite DNA, Spectral Analysis, Spectrograms.

Background: Spine gourd (Momordica dioica Roxb. Willd) is one of the important cucurbitaceous crops grown across the world for vegetable and medicinal purposes. Diseases caused by the DNA viruses are becoming the limiting factors for the production of spine gourd reducing its potential yield. For the commercial cultivation of the spine gourd, propagation material used by most o...

Recently, we discovered that alpha satellite DNA has unique and genus-specific localizations on the chromosomes of small apes. This study describes the details of alpha satellite localization in the genera Nomascus and Hylobates and explores their usefulness in distinguishing parental genome sets in hybrids between these genera. Fluorescence in situ hybridization was used to establish diagnosti...
متن کاملTwo Types of Alpha Satellite DNA in Distinct Chromosomal Locations in Azara's Owl Monkey
Alpha satellite DNA is a repetitive sequence known to be a major DNA component of centromeres in primates (order Primates). New World monkeys form one major taxon (parvorder Platyrrhini) of primates, and their alpha satellite DNA is known to comprise repeat units of around 340 bp. In one species (Azara's owl monkey Aotus azarae) of this taxon, we identified two types of alpha satellite DNA cons...
متن کاملReplication of alpha-satellite DNA arrays in endogenous human centromeric regions and in human artificial chromosome
In human chromosomes, centromeric regions comprise megabase-size arrays of 171 bp alpha-satellite DNA monomers. The large distances spanned by these arrays preclude their replication from external sites and imply that the repetitive monomers contain replication origins. However, replication within these arrays has not previously been profiled and the role of alpha-satellite DNA in initiation of...
