Adenine is one of the four bases in DNA that make up the letters ATGC, adenine is the "A". The others are guanine, cytosine, and thymine. Adenine always pairs with thymine.
Researchers have discovered a key protein that controls how stem cells "choose" to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels, according to a study published in the Proceedings of the National Academy of Sciences (PNAS).
In the past ten years, researchers in genome stability have observed that many kinds of cancer are associated with areas where human chromosomes break.
Researchers at Duke University's Pratt School of Engineering have uncovered a missing link in scientists' understanding of the physical forces that give DNA its famous double helix shape.
Imagine taking a vitamin for longevity! Not yet, but a Dartmouth discovery that a cousin of niacin prolongs lifespan in yeast brings the tantalizing possibility a step closer.
OrphageniX Inc., a new biotechnology company founded by University of Delaware researchers, has been established in Wilmington to develop and commercialize UD-patented technologies for repairing genes that cause rare, hereditary diseases such as sickle cell anemia and spinal muscular atrophy.
Over the past three years, numerous studies have shown that short pieces of single-stranded RNA, known as microRNAs, play a central role in the development of at least some cancers.
Researchers have found a possible way to protect people with multiple sclerosis (MS) from severe long-term disability: increase nervous-system levels of a vital compound, called nicotinamide adenine dinucleotide (NAD), by giving its chemical precursor - nicotinamide, a form of vitamin B3.
Fred Hutchinson Cancer Research Center, The Netherlands Cancer Institute (NKI) and Cancer Research Technology Limited (CRT) today have released details of the development and commercialisation of a powerful protein-genome interaction mapping technology termed 'DamID.'
Bacteria like Salmonella have a complicated immune system that helps them recognize and isolate foreign DNA trying to invade their cell membrane, according to a University of Washington-led study in the June 8 issue of Science Express.
Researchers have known for years that damaged DNA can lead to human diseases such as cancer, but how damage occurs - and what causes it - has remained less clear.
In this month's issue of the leading scientific journal Genome Research, scientists from Kyushu University report how environmentally damaged DNA may contribute to human genetic diversity.
Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation - an idea that has challenged some of the most basic concepts of modern biochemistry.
In a new study, Drs. Gil Atzmon and Nir Barzilai at the Albert Einstein College of Medicine of Yeshiva University have found that people harbor alleles--alternative forms of a gene--that confer the same sort of longevity advantage.
Whether depressed patients will respond to an antidepressant depends, in part, on which version of a gene they inherit, a study led by scientists at the National Institutes of Health (NIH) has discovered.
The wealth of information contained in a strand of genetic material boils down to sequences of matched pairs of nucleotides that cellular machinery decodes to construct proteins.
Researchers worldwide are seeking to define ancient sections of our genetic code that may soon be as important to medical science as genes.
A quarter century after they discovered it, researchers have identified the job of one of the most common DNA-damage response proteins. The enzyme has puzzled scientists because it is present in nearly every organism, which suggests that it is crucial to life, and yet, in laboratory experiments, its function has remained a mystery.
The results of a large study published today in the open access journal BMC Neurology reveal that multiple sclerosis (MS) patients are more likely to carry two specific genetic variations in the Early B-cell factor gene (EBF-1), than healthy individuals.
African-American women who carry the 10398A mitochondrial DNA allele are 60 percent more likely to develop invasive breast cancer than African-American females without that genetic marker, according to research published in the September 1 issue of "Cancer Research."
A Rensselaer researcher has developed a new tool to help unravel the function of an elusive DNA structure. The findings, which were presented today at the 230th national meeting of the American Chemical Society (ACS) in Washington, D.C., could lead to a better understanding of diseases such as cancer and diabetes.
