DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Genetic mystery of bacterium causing ‘Black Death’ revealed

Between 1347 and 1351 - a period of just five years, Europe's Black Death wiped out about 30 million people - 30 to 50% of the population on the continent. Now geneticists have reconstructed the genome of the bacterium that caused the plague. It is found to be an ancient strain of a bacterium called Yersinia pestis very similar to the strain the exists today.

Skin cell to liver cell shows promise for genetic liver disease

In a new scientific breakthrough, researchers have taken skin cells from a patient with liver disease and turned them into replacement liver cells. Although the procedure is years before it can be used in humans, but if approved, it could launch a new era of personalized therapies for serious genetic disorders.

Two-gene DNA urine test for prostate cancer

In the current debate sparked by the recent USPSTF recommendation on PSA screening, it is clear that better biomarkers than PSA are urgently needed. One new biotechnology that may go a long way in detecting only prostate cancer and reducing unnecessary prostate cancer biopsies and possible subsequent overtreatment, is the development of a new urine test for prostate cancer.

Chromosomal microarray can provide important information for patient treatment

Chromosomal microarray (CMA)—a powerful test for diagnosing the genetic abnormalities causing some types of developmental delay and birth defects—can be used in an evidence-based manner to provide important information for patient treatment, according to a pair of studies in the September issue of Genetics in Medicine, the official peer-reviewed journal of The American College of Medical Genetics.

New robust technique holds promise for identifying trace mutant DNA sequences

Molecular DNA testing methods offer clinicians powerful tools that serve to confirm or identify disease diagnoses. High sensitivity and high specificity, however, are frequently a challenge to achieve with these methods. In a study scheduled for publication in the November issue of The Journal of Molecular Diagnostics, researchers describe a new, robust technique that holds promise for identifying trace mutant DNA sequences in an overwhelming population of unmutated DNA.
