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.
When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionise the molecules even further. To fully understand how biological structures are affected by this radiation, it is important for physicists to measure how electrons are scattered during collisions.
A team of researchers from New Jersey Institute of Technology and Children's Hospital of Philadelphia have developed an algorithm through machine learning that helps predict sites of DNA methylation - a process that can change the activity of DNA without changing its overall structure - and could identify disease-causing mechanisms that would otherwise be missed by conventional screening methods.
Researchers from Sweden and Brazil have identified a novel mutation in a strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) obtained from a patient in Stockholm, Sweden, in late April.
Researchers from the University of Tsukuba show that long stretches of repeat DNA sequences in the gene FLI1 are associated with susceptibility to systemic sclerosis.
New genome-editing technologies developed by researchers in J. Keith Joung's laboratory at the Massachusetts General Hospital (MGH) have the potential to help understand disease-associated genetic mutations that are based on C-to-G (cytosine to guanine) single base changes.
Increasing the levels of a chemical found in all human cells could boost a woman's fertility and help select the best eggs for IVF, according to University of Queensland research.
A team of researchers from The University of Texas Health Science Center at San Antonio confirmed the role of a certain protein in the development of high-grade kidney cancer.
Familial spinocerebellar ataxia (SCA), Huntington disease, and spinal and bulbar muscular atrophy are inherited neurodegenerative diseases.
DNA damage in general and DNA strand breaks in particular occur every day in all cells of the human body.
A new study published on the preprint server bioRxiv in April 2020 reports the discovery of the structure of the cap created by the novel coronavirus on virally encoded mRNAs. The finding could help create new antiviral strategies.
Many common gut bacteria carry cancer-causing mutations, says a new study published in the journal Nature on the 27th February 2020.
Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body. Kempf
The reproductive years of a woman are at their peak before the age of 30. Beyond that, fertility starts to decline, and by the age of 40, fertility potential is about half the level it was before 30 years old. Many women experience fertility issues, but now a new study on mice may help reverse the clock on eggs, offering new fertility hope to older women.
Researchers have lifted fertility rates in older female mice with small doses of a metabolic compound that reverses the aging process in eggs, offering hope for some women struggling to conceive.
Echocardiography is a test that uses ultrasound techniques to produce images of the heart in real time. Stress echocardiography uses this technique to evaluate the heart rate response while performing an activity in which the heart has to work (stress).
Chronic kidney disease affects 750 million people each year. Aging populations and an increase in diseases such as diabetes will lead to a greater burden of kidney disease.
In clinical trials of adults with Huntington's disease (HD) the Q-Suite Motor Assessment Tool (Q-Motor) has proven to be helpful to detect and quantitate subtle motor abnormalities.
Mutations in the gene that encodes a protein called adenine nucleotide translocator (ANT) cause a variety of conditions, such as heart disease and weakness of the eye muscles, but the underlying mechanism of how these mutations trigger disease has been unclear.
A space-age metal that formed part of the asteroid that destroyed the dinosaurs could provide a new method of treating cancer tumors selectively using light.
DNA-based nanomachines are being created by DNA origami in several ways to create mechanical force at the scale of picoNewtons.
