In this assay, a hairpin probe (HP), which consists of the aptamer sequence of cocaine, is partially complementary to the primer. (rsc.org)

In eukaryotes, DNA methylation refers to the addition of a methyl group to the fifth atom in the six-atom ring of cytosine residues. (degruyter.com)
The best characterized chemical modification of DNA is the methylation of cytosine to 5-methylcytosine (5mC) that occurs almost exclusively in the context of a cytosine base linked by the DNA phosphate-backbone to guanosine, termed a CpG site. (frontiersin.org)

This recognition site structure leads to a symmetrical cleavage of both DNA strands and results in either blunt- or sticky-ends of the digested DNA. (neb.com)

And so it's important to know is that after cloning a gene, the DNA that was cloned can actually be used as a probe to detect the same sequence and an unknown DNA sample. (pearson.com)
And so we can take this radioactive DNA probe and we can put it into both of these samples and under the right conditions. (pearson.com)
The labeled DNA probe combines with amplicon to form stable RNA: DNA hybrids. (cdc.gov)
The biosensor chip -- consisting of a double stranded DNA probe embedded onto a graphene transistor -- electronically detects DNA SNPs. (nanowerk.com)
The chip consists of a DNA probe embedded onto a graphene field effect transistor. (nanowerk.com)
The DNA probe is an engineered piece of double stranded DNA that contains a sequence coding for a specific type of SNP. (nanowerk.com)
A DNA probe is a labeled fragment of DNA that contains a nucleotide sequence specific for the gene or chromosomal region of interest. (enzolifesciences.com)

Since then, he has been working as a postodoc in Dr. Wassenegger's lab (RLP AgroScience GmbH, AlPlanta) and his main field of interest is RNA-interference (RNAi) and RNA-directed DNA methylation (RdDM) in plants. (degruyter.com)
Carcinogenesis is accompanied by widespread DNA methylation changes within the cell. (frontiersin.org)
These properties make cancer-associated DNA methylation changes very attractive for development of cancer biomarker tests with substantive clinical utility. (frontiersin.org)
Cancer-associated DNA methylation changes can also be detected with accuracy in the cell-free DNA present in blood, stool, urine, and other biosamples. (frontiersin.org)
This review will summarize existing DNA methylation cancer biomarkers used in clinical practice across the application domains above, discuss what makes a suitable DNA methylation cancer biomarker, and identify barriers to translation. (frontiersin.org)

Putting their new concept of so-called 'Primer Exchange Reaction' (PER) cascades to the test, they successfully engineered a first set of devices with diverse functions, such as self-building DNA-origami and DNA nanostructures that sense, amplify, record or logically evaluate environmental signals. (nanowerk.com)
With DNA-PAINT it is possible to visualize all the strands in DNA nanostructures individually. (nanotech-now.com)
In the online journal Nature Communications, he and his colleagues describe a mode of super-resolution microscopy that enables all the strands within these nanostructures to be visualized individually. (nanotech-now.com)
The DNA-PAINT method thus provides a means of optimizing the construction of DNA nanostructures. (nanotech-now.com)

This overhang is designed to capture the PER cascades' second component, the "primer," which contains a region that is complementary to the overhang. (nanowerk.com)

Highly specific and effective gene silencing of any disease can be achieved by an accurate knowledge of the target mRNA sequence and rational design of its complementary antisense agents for the downregulation of its protein message. (genomicglossaries.com)
Improved performance of Pyrosequencing using single-stranded DNA-binding protein. (wikidoc.org)

Nanowerk News ) Bioengineers at the University of California, San Diego have developed an electrical graphene chip capable of detecting mutations in DNA. (nanowerk.com)
A highlight of this study is we've shown that we can perform DNA strand displacement on a graphene field effect transistor. (nanowerk.com)

Essentially, the method allows sequencing of a single strand of DNA by synthesizing the complementary strand along it. (wikidoc.org)
The chip essentially works by performing DNA strand displacement, the process in which a DNA double helix exchanges one strand for another complementary strand. (nanowerk.com)

Example of a pyrogram showing the nucleotide sequence in a specific section of DNA. (wikidoc.org)

Computer software helps them determine the specific sequence required to ensure the DNA folds into desired shapes. (materialstoday.com)

Combine such machinery with photonic sensors, electric circuits, and complex motion and dynamics, and you are well on your way to a nanorobot made from DNA-a nanorobot that not only mimics mechanical functions but also interacts with biological materials. (thebulletin.org)

It is therefore complementary to mRNA. (genomicglossaries.com)
