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.
In some neurological diseases, too much of what is usually a good thing can be bad, said researchers at Baylor College of Medicine in a report in this week's issue of the journal Cell.
Chemists at Ohio State University have gained new insight into how sunlight affects DNA. And what they found overturns ideas about genetic mutation that originated decades ago.
By discovering a crucial piece of submicroscopic information about how the brain converts fuel into energy for neurons, Cornell University biophysicists have gleaned new insights into brain cell metabolism that will allow neurologists to better interpret data from such diagnostic tests as positron emission tomography (PET) scans and a specialized magnetic resonance imaging (MRI) test.
By deciphering the ingenious mechanism used by a particular enzyme to modify bacterial chromosome chemistry, scientists have come a step closer to designing a new kind of drug that could stop virulent bacterial infections in their tracks. Their research will be published in the May 6 issue of the journal Cell.
One traditional approach to pharmaceutical design uses so-called “first messengers” – hormones, other natural facilitators or synthetic products – to initiate various cellular cascades for the desired physiological effect. To date, despite concerted efforts at all levels of research, this approach has failed to develop a truly successful obesity drug to address this major global health problem.
A controversial theory about how diabetes causes extensive tissue damage will appear in the November issue of Diabetes. At stake in the heated debate over the theory are researchers' efforts to find new ways to reduce loss of vision, kidney failure, heart damage and other side effects of diabetes.
Their finding explains how oxidative DNA damage - a process long believed to underlie cancers and aging - can create permanent genetic damage.
Biochemists at Duke University Medical Center have discovered key components that enable the cell's DNA repair machinery to adeptly launch its action in either direction along a DNA strand to strip out faulty DNA.
A laser-based microscopy technique may have settled a long-standing debate among neuroscientists about how brain cells process energy
NH-Dartmouth Medical School cancer researchers, in a fusion of biochemistry and genetics, have discovered a new vitamin in a molecular pathway central to such vital processes as gene regulation, metabolism and aging. And, they found that milk contains this nutrient.
A quick new technique able to identify genes that evolve rapidly as well as those that change slowly already has pinpointed new targets for researchers developing drugs against tuberculosis and malaria, and it could do the same for other infectious diseases, according to a paper in this week's Nature.
A century old mystery is taking place in your head as you read these words. Blood vessels in regions of your brain are widening, bathing cells in an increased blood flow.
