Highly Repetitive Satellite DNA
DNA Sequence, Satellite DNA, Cucumis melo The primary sequence of the prominent Cucumis melo satellite DNA is presented. The cloned Hind Ill-repeat unit has a length of 352 bp and a GC-content of 56%. Within this sequence an inverted repeat of 9 bp, including a 286 bp loop, and one direct repeat are shown. Several open reading frames are possible following the sequence in both directions whose ...
متن کاملSatellite DNA: An Evolving Topic
Satellite DNA represents one of the most fascinating parts of the repetitive fraction of the eukaryotic genome. Since the discovery of highly repetitive tandem DNA in the 1960s, a lot of literature has extensively covered various topics related to the structure, organization, function, and evolution of such sequences. Today, with the advent of genomic tools, the study of satellite DNA has regai...
متن کاملSchistosome satellite DNA encodes active hammerhead ribozymes.
Using a computer program designed to search for RNA structural motifs in sequence databases, we have found a hammerhead ribozyme domain encoded in the Smalpha repetitive DNA of Schistosoma mansoni. Transcripts of these repeats are expressed as long multimeric precursor RNAs that cleave in vitro and in vivo into unit-length fragments. This RNA domain is able to engage in both cis and trans cleav...
متن کاملSpectral Representations of Alpha Satellite DNA
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...
متن کاملNucleotide sequence of bovine 1.723 satellite DNA.
The nucleotide sequence of the bovine 1.723 satellite DNA repeated unit was determined. The 680 bp long period of this satellite DNA does not show any significant sequence similarities with the known bovine satellite DNAs. Short repetitive sequences which are parts of 680 bp long repeated units do not form any orderly periodical structure. It seems, however, that the basic repeated unit of the ...
