RFLP analysis requires that a probe to a specific area of DNA be used to identify specific locations. (cuny.edu)

As the cell performs its DNA repair procedures, CRISPR instructs it to use a different sequence instead of the original one, thereby editing the genome. (newatlas.com)
Cutting DNA could cause some unintended side effects , and concerns have been raised that CRISPR can make edits in the wrong section of the genome. (newatlas.com)

An acyclic connected graph (i.e. a tree) is constructed on a rectangular DNA origami substrate of 100 x 70 nm^2. (phys.org)
a) A straight line in the middle of the DNA origami was used as the test bed. (phys.org)
Such DNA origami structures are information-bearing nanostructures by nature with well-defined nanoscale geometry. (phys.org)

For instance, Brownian motion at the nanoscale can be controllably converted into directed movements within DNA-based nanomachines using DNA hybridization reactions. (phys.org)

Sanger sequencing is appropriate for analyzing fewer sites and fewer samples. (pristol.net)
We identified 78 (1.3%) samples with non-canonical haplotypes, which in 62 cases were paired with a canonical haplotype. (bmj.com)
Also, additional sequence information available for one of these samples showed a heterozygous SNP near exon 17, placing a 3′ limit on the size of the putative deletion. (bmj.com)
However, the DNA from these samples was not available. (bmj.com)
No significant difference in Shannon diversity for V1V3 (p = 0.22) and V3V5 (p = 0.11) sequences among paired samples was seen. (biomedcentral.com)
The DNA and RNA samples were sequenced. (citrusrdf.org)
Gradient and random S/pBrS copolymers made by RAFT showed similar Kerr constants, while those made by FRP and ATRP had Kerr effects different by a factor of two or more and were similar to those shown by samples with resultant blocky and random comonomer sequences made previously by BR of a-PS in poor and good solvents, respectively. (ncsu.edu)
To ensure that all possible microstructures, such as diad stereosequences in vinyl homopolymers and monomer sequences in copolymers, including their locations along polymer chains, that is, all macrostructures, are represented, it became necessary to generate samples with huge quantities (many many tons) of constituent polymer chains. (ncsu.edu)
this recommendation does not preclude the preparation of DNA samples for subsequent archiving if the material is considered potentially useful for future studies. (who.int)

Slopes of plots outside the drug binding sites can be used to identify locations of altered DNA structure. (syr.edu)
In this approach, unphased SNP genotypes are compared to pairs of canonical haplotypes to identify potentially hemizygous regions. (bmj.com)
A technique that amplifies (copies) DNA or RNA segments, in Amplification (NAA) order to directly identify microorganisms in sputum specimens. (cdc.gov)

And all of us who teach colloid and interface science find it natural to illustrate the usefulness of our subject with examples from everyday formulations that we may find in a kitchen, a bathroom or a garage. (lu.se)

NtbZIP s were unevenly distributed across twenty-two tobacco chromosomes, and we found sixteen pairs of segmental duplication. (biomedcentral.com)
In humans, somatic (nongerm) cell nuclei normally have 46 chromosomes in 23 pairs. (msdmanuals.com)
A karyotype illustrates the full set of chromosomes in a person's cells. (msdmanuals.com)

We figured that retrons should give us the ability to produce ssDNA within the cells we want to edit rather than trying to force them into the cell from the outside, and without damaging the native DNA, which were both very compelling qualities," says Daniel Goodman, co-first author of the study. (newatlas.com)

Students were required to evaluate characters on a basis of primitive and advanced, and construct cladograms that illustrated a hypothesized process of evolution. (haworthia.org)

The initial relative slopes of footprinting plots are proportional to the binding constant of the drug for its DNA sites. (syr.edu)
On non-metric multi-dimensional scaling plots, paired patient- and provider-collected swabs clustered closely. (biomedcentral.com)

The data provided herein can guide the use of these DNA reference materials in epigenomics research, as well as provide best practices for experimental design in future studies. (biomedcentral.com)
Here, the FDA's Epigenomics Quality Control (EpiQC) Group presents DNA methylation sequence data across all seven GIAB reference cell lines, as well as a comparative analysis of targeted and genome-wide methylation protocols, to serve as a comprehensive resource for epigenetics research. (biomedcentral.com)
By enhancing a DNA examination with transcriptome data, a multi-modality study of a particular patient's cancer is formed, yielding increased scientific/analytical rigor and potential insights. (biomedcentral.com)
We also illustrate the potential utility of MicrobeTrace in support of contact tracing by analyzing and displaying data from an outbreak of SARS-CoV-2 in South Korea in early 2020. (cdc.gov)
