DNA methylation can be measured both in specific genes and in repetitive DNA
sequences that are widespread throughout the genome (Bollati et al.
The centromere is functional, but it isn't wrapped in a blanket of repetitive DNA
, suggesting the repetitive elements aren't necessary for a centromere to function.
Using this approach, which takes advantage of the lower repetitive DNA
in the date palm gene regions, we have increased the publicly available knowledge of the date palm gene by about 1000 fold," he added.
Emanuel, Kurahashi and colleagues have detected other palindromic repetitive DNA
sequences at the breakpoints of other translocations, suggesting that these unstable structures may play a broader role in chromosome abnormalities beyond the t(11;22) rearrangement.
Polymerase chain reaction amplification of a repetitive DNA
sequence specific for Mycobacterium tuberculosis.
Because this region of chromosome 3 is thought to be caused by recombination between flanking segments of highly repetitive DNA
sequences, duplications of 3q29 should occur with the same frequency as deletions.
Finally, we used two repetitive DNA
elements, namely, Alu and LINE-1 repeats, to estimate global methylation.
The study found that the late blight genome is two and a half to four times larger than those of its relatives, mainly due to a massive amount of repetitive DNA
hESCs maintain telomere length by expressing the enzyme telomerase, the catalytic subunit of which, hTERT, adds telomeric repetitive DNA
sequences to the chromosome ends.
sequences are the source of many gaps in the sequences of other organisms, including the worm Caenorhabditis elegans (SN: 12/12/98, p.

The genes have also been designed to avoid features that are frequently problematic in protein expression such as mRNA secondary structure, repetitive DNA
elements and internal translation initiation sites.
