PCR Rap | sciencerapper

An ingenious technique called Polymerase Chain Reaction (PCR, in the labaratory vernacular) uses a Polymerase to selectively an cheaply amplify certain sequences of DNA from very small amounts of starting materials.  The invention of PCR piggy-backe don many existing technologies, and we have used PCR to learn many, many things about biology. The following rap about the Polymerase Chain Reaction that highlights a few things: the beautiful way in which DNA is copied (using enzymes called Polymerases) the great insight of Kary Mullis to create a useful tool that could copy DNA in monumental, [more...]

Rough Collie | Largest Pet Health and Medicine Information

Rough Collie (also known as the Long-Haired Collie) is a breed of dog developed originally for herding in Scotland. It is well known through the works of author Albert Payson Terhune, and latterly through the Lassie novel, movies, and television shows. There is also a smooth-coated variety; some breed organizations consider the smooth-coat and rough-coat dogs to be variations of the same breed. Three coat colors are recognized for Rough Collies: sable and white, where the “sable” ranges from pale tan to a mahogany; tricolour, which is primarily black edged in tan; blue [more...]

Episode 3: DNA Sequencing | SynBio Online

Episode 3 Audio MP3 Version AAC Version Synopsis DNA sequencing essentially starts by copying out the DNA bases, and then finding ways to read them one by one. This process is called “sequencing by synthesis”. Sequencing has many applications especially for human health, and can be used to discover new DNA parts that synthetic biologists can use.

Wikipedia clone and read about Somaclonal Variation

Structural changes in nuclear DNA Structural changes in nuclear DNA appear to be a major cause of somaclonal variation. The changes can modify large regions of a chromosome and so may affect one or several genes at a time. These modifications include the following gross structural rearrangements. Deletion: loss of genes Inversion: alteration in gene order Duplication: duplication of genes Translocation: segments of chromosomes moving to new locations. Activation of transposons can be a cause of somaclonal variation. Transposons or transposable elements are mobile segments of DNA that can [more...]

Lending new life to the demise of Louis XVI, scientists performed a battery of DNA tests on dried blood inside a decorative gunpowder gourd that purportedly contained one such handkerchief. The results, described Oct. 12 in the journal Forensic Science International: Genetics, show the blood belongs to a blue-eyed male from that time period: a possible dead-ringer for the executed king. “The next step is find a descendant either of the king or his mother,” said Davide Pettener, a population geneticist at the University of Bologna in Italy who helped with the analysis. “Otherwise [more...]

Simpson also brought in Barry Scheck (pictured below) and Peter Neufeld, the two most-knowledgeable attorneys on the planet regarding DNA evidence, which became a critical component — and arguably the most important legal legacy — of the trial. There was certainly no shortage of circumstantial evidence connecting Simpson to the murders. He had a long history of abusing his ex-wife, a point the prosecution drilled home in their opening statement by playing a frantic 911 call made by Mrs. Simpson, five years before the murders, when an enraged O.J. was banging on her door. The case ignited [more...]

Breast cancer is a malignant tumor of the mammary gland. In other words, a cancer that originates in the unit cell whose function is to secrete milk, units ducto-lobular breast, mainly in women (cancer occurs 200 times less frequently in humans, which also has breasts, although atrophy). This cancer is the most common cancer in women with 89 cases per 100 000 5 to 10% of these cancers have a genetic hereditary, 85 to 90% of cases (known as sporadic or non-hereditary) have misunderstood the origins, environmental.

According to the web page, that message has been displayed on the site since Thursday, March 06, 2008 at 4:00:57 PM. Why is Family Tree DNA partnered with a site that has been down for apparently seven months? I have also recently had several people complain that they have waited a long time for DNA test results from FTDNA. There must be something going on with them to be so disorganized. To top it off, after all of this waiting, they cannot tell us which Haplogroup Charlie belongs to and there are only eight matches in their database of 139,861 Y-DNA records at the 12-marker level (but all [more...]

National DNA database and psychiatric patients | Frontier Psychiatrist

The advent of DNA analysis as a powerful tool for crime detection has led to the creation of England and Wales’s National DNA Database (NDNAD). This is one of the world’s largest databases of DNA information, storing profiles of nearly five million individuals (1). We write to raise a concern about the potential impact of this database on people with mental disorders. The NDNAD has long been the subject of scrutiny and criticism with regards to how DNA profiles are collected and retained and from whom. This is because the current regulations on DNA profile collection mean that the NDNAD [more...]

Living garden on bus rooftop to add some rolling green to city streets Finding room for green spaces in more and more crowded cities isn’t easy but NYU graduate student Marco Castro Cosio has hit upon the idea of planting gardens on some previously wasted space found on city streets – the roofs of buses. With New York’s Metropolitan Transportation Authority (MTA) running a fleet of around 4,500 buses, each with a surface area of 340 square feet (31.5 m2), Cosio says that if a garden was grown on the roof of every one, there would be an extra 35 acres of rolling green space in the [more...]

Dienekes' Anthropology Blog: Running EURO-DNA-CALC on GenomesUnzipped

genomesunzipped is a new initiative to put data of personal genomics customers online. It's a great idea, and the data will be quite useful to many people. I downloaded the available data and ran EURO-DNA-CALC on them. Of course it is meant to be used for European or West Eurasian people, which all of them seem to be. Here are the results for the 12 people whose data were online as of this writing. In bold are components whose confidence intervals do not intersect 0. Most of them seem to be of NW European descent as their names suggest, and a couple seem to be partly or significantly of [more...]

Sandwalk: Nobel Laureate: Walter Gilbert

The Nobel Prize in Chemistry 1980. "for their contributions concerning the determination of base sequences in nucleic acids" Walter Gilbert (1932 - ) was awarded the Nobel Prize for developing a chemical method of sequencing DNA (with Allan Maxam). The method relied on chemical reactions that cleaved DNA at specific residues. By carrying out partial reactions where only one cleavage occurred in each DNA strand, it was possible to separate the cleavage products on an acrylamide gel and determine the position of each residue by the length of the fragment. The chemical sequencing strategy has [more...]

Xiang-Jun's Corner: Further details of the DNA story revealed by ...

I read Watson's "The Double Helix" book a while ago, and overall I am quite familiar with the DNA story. Still, I found this account fascinating: it provides a "CAST LIST" in "The search for the structure of DNA" with photos (p521); and it succinctly summarizes the relationships among the key players. In science, no other story shows more dramatically the collaborative and competitive nature among scientists working on similar projects. Franklin’s X-ray diffraction photograph 51 of B-form DNA (see figure above, from Wikipedia), with its unambiguous evidence that DNA was helical, proved [more...]
