New Paper Shows Enzyme-Controlled Movement of DNA Polymer Through ...

This paper addresses a key challenge for DNA strand sequencing: fine control of the translocation of the DNA strand through the nanopore, at a rate that is consistent and slow enough to enable accurate identification of individual DNA bases. The Nature Nanotechnology work shows for the first time that the motion of a strand can be controlled using electronic feedback and that an enzyme can move a strand against a field while located on top of the nanopore. "The techniques described in this paper are an advance towards electronic, single molecule DNA sequencing of DNA strands" said [more...]

Evaluation of Five Methods for Total DNA Extraction from Western ...

DNA extraction is a routine step in many insect molecular studies. A variety of methods have been used to isolate DNA molecules from insects, and many commercial kits are available. Extraction methods need to be evaluated for their efficiency, cost, and side effects such as DNA degradation during extraction. Methodology/Principal Findings From individual western corn rootworm beetles, Diabrotica virgifera virgifera, DNA extractions by the SDS method, CTAB method, DNAzol® reagent, Puregene® solutions and DNeasy® column were compared in terms of DNA quantity and quality, cost of materials, [more...]

Legislation Watch: Crimes Amendment (Forensic Procedures) Bill 2010

Elucubrator,  7 October 2010 12:54 PM I'm not sure of the purpose of this Bill: it smacks a little of grandstanding. Today is the last day that Parliament sits before the election is held on 24 November, when the Parliament is prorogued. At Bills before the House will then lapse, and must be re-introduced in the next session. That is — back to square one for the whole process. Perhaps the ALP is just testing the water?

In Cancer, One Ring To Rule Them All

Imagine that a machine draws your blood, screens it for genetic mutations and chemical variations that can cause cancer, and then pops out a drug tailor-made for your DNA. The hypothetical drug would target and fix the point irregularities which have accumulated over time that can lead to the formation of tumors — and cancer. "Personalized cancer drug delivery? Depending on the approach, it could be as soon as 10 to 15 years away," says Viterbi professor Andrea Armani , an assistant professor of the Mork Family Department of Chemical Engineering and Materials Science.

Ultrasensitive DNA detection

Rapid and sensitive DNA detection methods have a wide range of uses from cancer and disease diagnosis to the detection of harmful bacteria in food and drink. Previous methods rely on optical methods and a time consuming pre-amplification of the sample, which while sensitive often take several weeks and require bulky apparatus. Electrochemical methods have been used to improve the speed and portability. Now, Elena Ferapontova, Kurt Gothelf and colleagues at Aarhus University have developed a lipase-based electrochemical technique that can detect as little as 20 attomoles (2 x 10-17 moles) of [more...]

DNA Fingerprinting Not Exactly Reliable in Forensics

The incredibly small amount of DNA in samples and pressure to gain a conviction can lead to bias, according to an investigation by New Scientist, reports the Daily Mail. The magazine sent a sample of DNA from a real crime scene to 17 experienced analysts in a US lab. The experts’ differing results cast doubts over the technique’s reliability. The sample, from a gang rape, had already been used to convict a man but only one of the 17 scientists came to the same conclusion. Itiel Dror, a University College London scientist, who helped set up the investigation, said: ‘It is time DNA [more...]

DNA is a duplex, therefore the patient's DNA, labeled with a dye, will hybridize to DNA on the array. The investigators then treat the array with an enzyme called a mismatch endonuclease that will seek out and digest any places in the DNA duplexes that contain mismatches, thus identifying the mutation's location.  “You take someone’s genomic DNA, chop it up, label it using a florescent dye, and hybridize it to the microarray so that complementary features on the array can bind with the labeled DNA,” explained Manak. “Treatment with the enzyme results in cleavage at the mismatches, [more...]

How Fingerprinting Helps In DNA Paternity Testing

This form of fingerprinting method is also known as DNA profiling. Using this technique, the individuals are identified on the basis of their unique DNA profiles. This DNA profiling is done by analyzing the VNTR sequences. It stands for variable number tandem repeats. This sequence is found to be different in individuals except in twins. As per the facts mentioned above, the DNA samples of the child will exhibit the similar VNTR loci as that of their parents. This fingerprinting helps in identifying that whether the known father of a child is genuinely his biological dad. In fact, it is [more...]

Science Seminar - Ancient DNA

From just a few grams of ancient sediment, it is possible to reconstruct the environment in disparate places at different times. This is possible by extracting total DNA from sediments and looking for the genetic signals of various organisms that contributed to the mix. By comparing the signals with reference databases, identification to genus and species level of plants and animals is often possible. Such information can inform theories of niche stability, extinction dynamics and environmental change, and are therefore complimentary to existing methodologies such as pollen and macrofossil [more...]

DNA fingerprinting, help explain the idea and logic

“DNA fingerprinting” is a recently-introduced biochemical procedure that uses a pattern derived from a person’s genetic material to match a suspect’s genetic material against that of a specimen from a crime scene. Proponents have claimed astronomically high odds against obtaining a match by chance alone. These odds are based on an assumption that there is independence between the different characteristics represented by a single pattern. Which one of the following, if true, casts the most doubt on the claim of the proponents of DNA fingerprinting? (A) The large amount of genetic [more...]

PLoS ONE: Analysis of Short Tandem Repeats by Parallel DNA Threading

Abstract TopThe majority of studies employing short tandem repeats (STRs) require investigation of several of these genetic markers. As such, we demonstrate the feasibility of the trinucleotide threading (TnT) approach for scalable analysis of STRs. The TnT method represents a parallel amplification alternative that addresses the obstacles associated with multiplex PCR. In this study, analysis of the STR fragments was performed with capillary gel electrophoresis; however, it should be possible to combine our approach with the massive 454 sequencing platform to considerably increase the [more...]
