DURHAM, N.C. -- Each time a human cell divides, it must first make a copy of its 46 chromosomes to serve as an instruction manual for the new cell. Normally, this process goes off without a hitch. But from time to time, the information isn't copied and collated properly, leaving gaps or breaks that the cell has to carefully combine back together.

Researchers have long recognized that some regions of the chromosome,called "fragile sites," are more prone to breakage and can be a breeding ground for human cancers. But they have struggled to understand why these weak spots in the genetic code occur in the first place.

A comprehensive mapping of the fragile sites in yeast by a team of Duke researchers shows that fragile sites appear in specific areas of the genome where the DNA-copying machinery is slowed or stalled, either by certain sequences of DNA or by structural elements. The study, which appears May 5 in Proceedings of the National Academy of Sciences, could give insight into the origins of many of the genetic abnormalities seen in solid tumors.

"Other studies have been limited to looking at fragile sites on specific genes or chromosomes," said Thomas D. Petes, Ph.D., the Minnie Geller professor of molecular genetics and microbiology at Duke University School of Medicine. "Ours is the first to examine thousands of these sites across the entire genome and ask what they might have in common."

The term "fragile sites" was first coined in the 1980s to describe the chromosome breaks that appeared whenever a molecule called DNA polymerase - responsible for copying DNA -- was blocked in mammalian cells. Since that discovery, research in the yeast Saccharomyces cerevisiae has shown that certain DNA sequences can make the polymerase slow down or pause as it makes copies. However, none of them have shown how those delays result in fragile sites.

In this study, Petes wanted to find the link between the copier malfunction and its genetic consequences on a genome-wide scale. First, he knocked down the levels of DNA polymerase in yeast cells to ten-fold lower than normal. Then he used microarray or "gene chip" technology to map where segments of DNA had been rearranged, indicating that a fragile site had once been there.

After finding those fragile sites, his laboratory spent more than a year combing through the literature for any recurring themes among the genomic regions they had uncovered. Eventually they showed that the fragile sites were associated with sequences or structures that stalled DNA replication, esoteric entities such as inverted repeats, replication termination signals, and transfer RNA genes.

Where DNA's copy machine pauses, cancer could be next

KOTA SAMARAHAN: In the last few decades, the term DNA has grown to become a household name. But not many are aware that DNA, which stands for the mouthful deoxyribonucleic acid, can be extracted from an organism using common household items and tools found in the kitchen.

Visitors to the three-day BioBorneo 2014 Conference and Exhibition, currently held at University Malaysia Sarawak (Unimas), were surprised to know that DNA extraction is in fact a simple procedure that does not require sophisticated tools from the ivory tower of science.

At the exhibition booth hosted by the Malaysian Biotechnology Information Centre (Mabic), project officers Shamira Shamsudeen and Farah Nazri demonstrated yesterday how the DNA extraction procedure could be executed using household detergent, baking powder, meat tenderizer, a spoon and an electric blender.

The Mabic booth attracted many visitors who were keen to try out the DNA extraction technique themselves. Using the simple ingredients and kitchen tools, many visitors turned genetic scientists as they attempted to extract the DNA from a strawberry.

Speaking to The Borneo Post, Mabic executive director Dr Mahaletchumy Arujanan, says her centre aims to bring science closer home to the public.

She says it is important for the man in the street to feel at ease with the evolving new sciences and not to have misgivings and misconceptions.

Since the last few decades science has advanced so rapidly, especially with the advent of biotechnology, which has raised many contentious questions in areas such as stem cell technology, cloning and genetic modification of plants and animals, says Mahaletchumy.

These new sciences continue to be a cause clbre and that is because public understanding of science, especially biotechnology is at an infancy stage. The word DNA itself engenders a degree of fear among the public who mindlessly associate it with cloning and call it Frankenscience.

This is callous and insensitive as the discovery of the double-helix (DNA) has brought many benefits to humanity especially in the areas of medical science and agriculture, she says.

Extracting DNA as easy as ABC

DNA sequencing can already tell us a lot about our ancestorsbut now, a new technique developed by an international team of scientists allows them to pinpoint a person's geographical origingoing back 1,000 years.

The Geographic Population Structure (GPS) toolslightly confusing, admittedlybeats previous best attempts to tie location to DNA. It can track populations back to the islands or villages they descend from, with a 98 percent success rate, compared to within about 500 miles for old methods.

By studying admixturewhich is where two previously separate populations begin to interbreed and create a new gene poolthe team are able to understand where and when changes to historic DNA took place. In fact, they use 100,000 DNA signatures which are typical to specific geographical regions, and then compare these to autosomal chromosomes of a person being tested. Talking to Gizmag, Dr. Eran Elhaik from the University of Sheffield explained:

"We were surprised by the simplicity and precision of this method. People in a given geographical area are more likely to have similar genetics. When they also have genetic traits typically found in other, distant regions, the geographical origin of those traits is generally the closest location where those traits can be found."

The research results, published in Nature Communications, are certainly impressive. In one test, the team could place 25 percent of residents of 10 villages in Sardinia to their specific villages, and the other 75 percent to within 31 miles. In 20 islands within Oceania, they could track 90 percent back to their exact island.

It's not just a neat party trick, though. The development should help us understand a patient's ancestry better than ever, which should help improve our und knowledge of susceptibility to certain genetic diseases. Perhaps best of all, anyone can use it: If you have your autosomal DNA genotypedwhich costs $100-200if you have it done privatelyyou can uploads your DNA data to the GPS website to understand your ancestry.
