Welcome to the DNA Barcoding Blog!
Welcome to our new DNA barcoding blog. It truly is an exciting time to be involved in this aspect of genomic science as DNA barcoding has been used to identify new species, help explain the biodiversity of our planet and even detect food fraud. Just as a universal product code (UPC) identifies an item for sale in a store, a DNA barcode uniquely identifies each species of living thing. The DNA barcoding technique includes extraction of DNA from an organism of interest, ampliflication of this DNA through PCR (Polymerase Chain Reaction), and sequencing of the DNA at specific locations in the genome.
In 2008, students from the Trinity School in New York City used DNA barcoding to find out that the raw tuna being sold at some sushi restaurants and grocery stores was not actually “tuna”, but instead “tilapia”, which is a cheaper fish. This type of experiment not only demonstrates the real life applications of DNA barcoding, but just as importantly, shows the accessibility of this type of science to high school students.
This year, students from the New York City area will embark on the first ever Urban Barcode Project (UBP), a high school competition in which students will use DNA barcoding to explore the biodiversity in New York City. If you are a NYC teacher or a scientist interested in leading a team of students, please go to the UBP website for more information.

Jumping Down the Road to Cancer.
about 12 years ago - No comments
Lying dormant in our genomes are millions of jumping genes. Originally discovered by Barbara McClintock, transposons are DNA sequences that can move from one location to another in our DNA. Transposons cause mutations when they jump to new locations, so keeping them from jumping is important. However, although transposons are largely silent, every person probably…
When is a clone not a clone? When it’s a mosaic.

For the last decade or so, progressive cancer treatments involved taking samples of tumors, testing the cells to determine the genetic makeup, and then prescribing medicines targeted to specific mutations. There are many benefits to this approach, but it doesn’t always work. It turns out that tumors aren’t uniform; they are mosaics of cells that…
Jumping genes in your brain?
about 12 years ago - No comments
Mobile chunks of DNA that walk their way from one position in the genome to another may affect neurological diseases and could have subtle influences on normal brain function and behavior, according to a recent study in Nature. Alu is an example of a so-called “jumping gene” – a transposable DNA sequence that “reproduces” by…
DNA sequencing helps discover cavemen’s tools and diet
about 12 years ago - No comments
In the 1970s a team of archaeologists led by Carl Gustafson unearthed the remains of a single, 3-ton, male mastodon (Mammut americanum, a close relative of mammoths and elephants), hunted and butchered by a group of men at the Manis site in the state of Washington, USA (Gustafson 1979). Among the mastodon remains they found…
Evolution – Got Milk?
about 12 years ago - No comments
After asking students during a lesson on mutations if it is possible that a mutation in DNA could be good, most students will nod yes without much understanding. Recently, I finally had one student raise his hand immediately and answer the question (with extreme surprise that no other students were blurting out the answer)…”evolution!” He…
What do you get when you cross an immunologist, a nanotechnologist, and a geneticist? A DNA nano-robot!
about 12 years ago - No comments
Welcome to the world of nanobiotechnology and translational research… In a brilliant example of multidisciplinary research, Harvard Medical School’s Shawn Douglas, Ido Bachelet, and George Church combined forces to build nanostructures that would mimic the body’s immune system to recognize cancer cells and trick them into self-destructing. Their research is published today in Science but…
Hibernation – Why Not Me?
about 12 years ago - No comments
It’s the season of hibernation, something I’ve always wished I could do. Oh, to wrap up in a ball, sleep away the winter, and wake to a beautiful spring day – like Bambi! Although the thought has always intrigued me, it never really occurred to me what a feat hibernation actually is. It turns out…
Controlling gene expression through diet
about 12 years ago - No comments
Epigenetics is the study of chemical reactions that control the on and off switch of genes at specific times and the factors influencing them. Environment is a factor that influences epigenetic change which may encompass behavior, stress or diet. The easiest of the three to make observations from is diet. When we think of food,…
A virus in my meal?

Could the meat in your plate pose a health risk for you? If the animal where it came from was properly raised and handled, and the meat went through a sanitary inspection before reaching your plate, there is little chance it can cause you a health problem. But, what could happen if a sanitary authority has…
