FamilyTreeDNA.com: New Family Finder test officially launched

Tracing the Tribe is a blog about Jewish genealogy - All the developments, tools and resources you'll need to peer more closely into your family tree. Created in 2006 at JTA's request, it is now independent. As of today, FamilyTreeDNA.com's new Family Finder test has been officially launched. The new test connects family members across all ancestral lines, not only paternal or maternal. It represents a major advancement over earlier genetic genealogy tests. Everyone, regardless of gender, can now look for connections including grandparents, aunts and uncles, half siblings, and first, [more...]

The effect of DNA signals on nucleosome formation, chromatin ...

Much of the human genome is non-coding and it seems likely that at least some of the non-coding DNA is functionally important. However, only little is known about the possible function of the bulk of the human genome. Since essentially all the nuclear DNA is packaged into chromatin, it is likely that functional effects of non-coding DNA are mediated by the chromatin structure. By making use of human genomic sequence information now available, we showed that a specific set of periodic DNA motifs (period-10 VWG/CWB) encoded in genomic DNA is predicted to influence human chromosome function. The [more...]

Neandertal DNA and Proteins

With the completion of the Neandertal genome by the team of Dr. Svante Paabo and a closer look at their proteins by Gregory Hannon’s team at CSHL, scientists reveal incredible similarities between Neandertals and humans. Neandertals, the extinct species of what are most likely our closest relatives, lived on earth at the same time as our human ancestors but died out about 30,000 years ago. With the sequence of their genome now complete, we can compare the DNA to humans and chimpanzees to learn more about what makes humans unique as a species. The discovery of fossils is an exciting link to [more...]

Targeted sequence capture - Nimblegen + GS Junior - SEQanswers

Mutation Rate In Humans Gets Measured By Direct Sequencing

With better measurements of mutation rates, we could improve the calibration of the evolutionary clock, or test ways to reduce mutations, for example. Even with the latest DNA sequencing technology, the researchers had to design a special strategy to search for the vanishingly rare mutations. They used next-generation sequencing to establish the order of letters on the two Y chromosomes and then compared these to the Y chromosome reference sequence. Having identified 23 candidate SNPs – or single letter changes in the DNA – they amplified the regions containing these candidates and [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...]

A new portable DNA analyzer performs real-time analysis of blood samples left at the scene of a crime. Researchers at the University of California, Berkeley, developed the device, which packs microfluidics, electronics, optics, and chemical detection technology into a single briefcase-sized unit. "While previous groups have developed lab-on-a-chip systems, none of them have succeeded in making a completely portable, robust system that can be used at a scene," says team leader Richard Mathies.

While working at the National Institutes of Health in the early 1990s, Venter developed a way to rapidly discover genes by exploiting snippets of DNA called expressed sequence tags. In 1992, he founded The Institute for Genomic Research, and, three years later, he and a team decoded the first genome of a free-living organism. That led to Venter’s best-known breakthrough, mapping the human genome. Last May, he achieved a defining moment in the history of biology when he inserted digitally created DNA into a living bacterium, forming the first synthetic life.

Whiskey Tango Foxtrot Oscar: Swearing at an oath

With this definition in mind, the evil that Israel has done becomes manifest. The legislation reeks of injustice. It only applies to one subset of Israel, to the Arab minority.  It is clearly targeted toward them. It is making a blanket claim that all Israeli Arabs are forthwith considered fifth columnists. By legislative fiat Israel has now declared that Arab subversion of the Jewish state is now passed down genetically, just like Mitochondrial DNA. All Arabs are guilty of treason without exception and must prove by solemn oath otherwise. The law ironically is disobedient to the rules of [more...]

Asbestos Damage – Asbestos Dust And Dna Damage

You can buy asbestos test kits in any home store inexpensively. And as a matter of fact, they are relatively easy to use. But are they providing you with reliable results? Before we get into that question, let’s have a brief look at the material asbestos and why we still need to be mindful of the environment we are living in. Asbestos occurs in nature. It is a fibrous and friable material. Friable means that it can be broken up very easily into smaller pieces with using only very little amount of pressure. On the other hand, asbestos has been used in the manufacturing process of a wide [more...]

Berkeley Lab News Center Press Release: New Electrostatic-based ...

In a typical experiment, a microarray is prepared and mounted in a well chamber and the DNA is hybridized (a standard technique in which complementary single strands of DNA bind to form double-stranded DNA "hybrids"). A suspension of negatively-charged silica microspheres is then dispersed through gravitational sedimentation over the microarray surface, a process which takes about 20 minutes. Because the substrate or background surface of the microassay is positively charged, the silica microspheres will spread across the entire surface and adhere to it. However, on surface areas containing [more...]

Electrostatic trap catches tiny particles - physicsworld.com

Since their invention about 40 years ago this technique has been used with great success in biophysics, helping researchers to unravel the complex elasticity and folding dynamics of DNA, for instance. But, because optical tweezers struggle to hold on to objects that are significantly smaller than the wavelength of light, they cease to work for objects that are smaller than 100 nm. Charge rather than size Now, a group at ETH Zurich has developed an alternative mechanism for trapping particles that does not suffer from the same limitation.

Dr. Falk appears to be too hasty in his assumption that pseudogenes have "no function" and thereby show evidence for common ancestry.

As one news article said when reporting on the results of the ENCODE project in 2007: The findings, from a project involving hundreds of scientists in 11 countries and detailed in 29 papers being published today, confirm growing suspicions that the stretches of 'junk DNA' flanking [more...]

(Nanowerk News) In an innovation critical to improved DNA sequencing, a markedly slower transmission of DNA through nanopores has been achieved by a team led by Sandia National Laboratories researchers. Solid-state nanopores sculpted from silicon dioxide are generally straight, tiny tunnels more than a thousand times smaller than the diameter of a human hair. They are used as sensors to detect and characterize DNA, RNA and proteins. But these materials shoot through such holes so rapidly that sequencing the DNA passing through them, for example, is a problem. In a paper published this week [more...]

To harness this powerful single-molecule detection modality for high-throughput DNA sequencing, each of the four nucleotides (A, C, G and T) in the target DNA has to be converted into a predefined sequence of oligonucleotides, using a technique called Circular DNA Conversion. Each pre-defined sequence is then hybridized to a self-quenching molecular beacon.In their experimental setup, the Meller team recorded DNA translocation through a 4nm pore in a SiN membrane immersed between two aqueous solutions. With the camera in place, the researchers were able to detect florescence bursts in two [more...]
