Sentences with phrase «dna than the technique»

Neuberger & Partners suggests there are much easier ways to frame someone using DNA than the technique outlined by the Nucleix study.

Not exact matches

The idea of DNA sweeps or «dragnets» originated in Europe, and police departments have employed the technique more than a dozen times in the United States, typically stirring controversy.

At that time, techniques such as plant transformation and protein engineering using recombinant DNA techniques were established but less common place than they are today.

As they report in their paper, SPRNT is more than seven times more sensitive than existing techniques to measure interactions between DNA and proteins.

Parkinson contends that targeted gene replacement produces cells having specific genetic alterations far more effectively than the traditional technique for making transgenic animals, which entails injecting DNA into cell nuclei.

One of the new techniques used was chromosomal microdissection, in which a glass needle snips out the targeted area of a chromosome — a length of DNA less than one trillionth the weight of a paperclip.

The single - cell technique is better at detecting subtle mosaicism than usual DNA sequencing methods, which sequence many thousands or millions of cells mixed together and read out an average for the sample.

The resulting «designer nanotubes,» she adds, promise to be far cheaper to produce on a large scale than those created with so - called DNA origami, another innovative technique for using DNA as a nanoscale construction material.

Previous attempts to get DNA from parchment did not work well, but by using modern sequencing techniques, researchers can now get abundant livestock DNA from parchment, such as the 16th century deed from Lancashire, U.K., shown above, the team reports online today in the Philosophical Transactions of the Royal Society B. Not only is parchment plentiful, but as a legal document, it also has been carefully stored and often dated, making it a more readily available source of ancient DNA than bones.

The new study demonstrated the advantages of an in vivo DNA barcoding technique, which attaches small snippets of DNA to different lipid - based nanoparticles that are then injected into living animals; more than a hundred nanoparticles can be tested in a single animal.

She quoted Edward Holmes, a leading scientist at the HIV - sequencing laboratory at the University of Edinburgh, as saying that using viral genetic data for forensic science is much more complex than other techniques, such as DNA fingerprinting.

Because STRs are shorter than the stretches of DNA used in earlier profiling techniques, they can be useful even after chromosomes have begun to break down.

Xu applied the DNA microarray technique to screen more than 100,000 genes in the human genome to find the exact gene regulation pathway.

But isotopes overlaid with DNA tracking might provide firmer, finer - grained identifications than either could alone — if the practitioners of both techniques can collect a large enough database.

Applying their new techniques to the samples, the team was able to recover DNA fragments, 95 percent of which were shorter than 50 base pairs, Meyer says.

Using high - throughput DNA sequencing techniques, the research team looked at these functional elements in more than 1,000 data sets produced from over 100 mouse cell types and tissues.

By the 1990s, DNA testing had advanced somewhat through the use of restriction fragment length polymorphism, but that technique required more material than was available.
