... egg cells. He showed that in the cattle genome these breakpoint regions are rich in repetitive sequences and segmental duplications and include species-specific variations in genes associated with ...
... maize genome sequence is now complete thanks to a decoding effort so challenging even ... due to an unprecedented number of long strings of repetitive sequence and highly conserved transposable elements ...
... tissue-specific genes, non-coding regions of the genome that are normally “silent,” and repetitive sequences in the genome, which comprise the majority of the mammalian genome but are also normally ...
... has shown that genes constitute only a very small proportion of complex genomes, with repetitive sequences and (in particular) mobile genetic elements or transposons making up a much larger part. ...
... us," he noted.
Using a technique known as sequencing by synthesis (SBS), provided by Illumina in Hayward, ... class of RNAs mainly functions to repress repetitive sequences, including mobile DNA elements ...

The GIS study also highlighted the functional importance of portions of the genome that are rich in repetitive sequences.
"Because a lot of the biomedical research use model organisms such as mice ...
... and colleagues measured the level of tumor DNA methylation in a section of DNA containing repetitive sequences that are normally methylated, called long interspersed nucleotide element-1 (LINE-1), ...
... these benefits."
Plant DNA is often notoriously difficult to analyze because of large sections of repetitive sequence and sorghum was no different. Jeremy Schmutz of the DOE JGI partner HudsonAlpha ...
... key to whether the Huntingtin gene is normal or defective lies in a kind of genetic stutter: a repetitive sequence of the DNA triplet CAG, which codes for the amino acid glutamine. Stretches of CAG " ...

"Telomeric DNA has a repetitive sequence that can form unusual DNA structures ... to study because no specific DNA sequence preceeds or follows them," she says. "In constrast, ...

Conversely, in repetitive sequences, the bases alternated regularly, and the group found that these sequences bind ...
... segment of DNA was found in the chromosome's heterochromatin, a densely packed region of highly repetitive sequences of junk DNA near the chromosome's center.
During the embryo's initial divisions, ...
