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).

Understanding mechanism of SIRT6 activity may help treat diabetes and cancer

A study investigating how a cellular enzyme affects blood glucose levels in mice provides clues to pathways that may be involved in processes including the regulation of longevity and the proliferation of tumor cells.

New effort to produce standardized DNA parts for reducing development time of synthetic biology in labs

With seed money from the National Science Foundation (NSF), bioengineers from the University of California, Berkeley, and Stanford University are ramping up efforts to characterize the thousands of control elements critical to the engineering of microbes so that eventually, researchers can mix and match these "DNA parts" in synthetic organisms to produce new drugs, fuels or chemicals.

Researchers explain how HSV dismantles host's defense systems

A viral infection is like an uninvited, tenacious houseguest in the cell, using a range of tricks to prevent its eviction. Researchers at the Salk Institute for Biological Studies have identified one of the key proteins allowing herpes simplex virus (HSV) DNA to fly under the radar of their hosts' involuntary hospitality.

DNA testing can help individuals make more-informed health and lifestyle decisions

Mention the term “genetic testing” and reactions can vary widely—from curiosity, to reticence or anxiety, to enthusiastic acceptance. The reality is, DNA testing has been used for decades, primarily to determine the paternity of children and to obtain forensic evidence for police investigations and legal trials.

TUM biophysicists map changes in energy landscape of zipper-like protein molecule

Biophysicists at TUM, the Technische Universitaet Muenchen, have published the results of single-molecule experiments that bring a higher-resolution tool to the study of protein folding. How proteins arrive at the three-dimensional shapes that determine their essential functions - or cause grave diseases when folding goes wrong - is considered one of the most important and least understood questions in the biological and medical sciences.

New white paper examines how PCR mycoplasma tests and analysis save time and money

Contamination by mycoplasmal organisms is an ever-present concern in biopharmaceutical manufacturing. Their properties make them ready sources of contamination, while rendering them difficult and time-consuming to detect. A new free white paper, examines how PCR mycoplasma tests and analysis, deployed by a cutting-edge laboratory, minimizes testing delays and enable safe, high-volume biopharmaceutical production.
