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.
The current pandemic of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is still spreading rapidly throughout the world. A new preprint on the bioRxiv* server describes the structure of an important viral non-structural protein NSP12-16 and its role in SARS-CoV-2 infection.
A new study in the Journal of dietary supplements shows that nutritional supplements, including several vitamins and the mineral zinc, may be useful in preventing the infection or reducing its severity if caught.
A team of scientists from the USA and Germany has recently studied the evolution of SARS-CoV-2 in a representative set of sequences from the USA collected between 2020 and 2021. The findings reveal that the viral genome has accumulated multiple mutations over time with only occasional loss of mutation. The main driving forces behind such genetic variations include widespread infection and superspreader events.
New research from the University of Iowa and University Hospitals Cleveland Medical Center demonstrates that offspring can be protected from the effects of prenatal stress by administering a neuroprotective compound during pregnancy.
In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature biosensors and drug-delivery containers.
There is growing evidence to support the hypothesis that there is a neurodevelopmental component to the late-onset neurodegeneration occurring in the brain of huntingtin gene (HTT gene) mutation carriers, and that this increased susceptibility to brain cell death begins during childhood.
Just like other organisms, plants must respond dynamically to a variety of cues over their lifetime. Going through different developmental stages, or altering their form in response to a drought or drastic temperature change requires altering which of their genes are expressed into proteins and when those processes occur.
More than a dozen drugs are known to treat symptoms such as hallucinations, erratic behaviors, disordered thinking and emotional extremes associated with schizophrenia, bipolar disorder and other severe mental illnesses.
For their growth, cells need various nutrients and vitamins. So-called solute carriers (SLC), proteins that can transport such substances across the boundaries of cellular membranes, play a central role in metabolism.
Studies conducted in yeast show that exposure to ultraviolet light (UV) induces new types of DNA damage that may cause the deadliest form of skin cancer, malignant melanoma.
A breakthrough study, led by researchers from the University of California, Irvine, results in the restoration of retinal and visual functions of mice models suffering from inherited retinal disease.
Penn Medicine researchers have solved a decades old mystery around a key molecule fueling the power plant of cells that could be exploited to find new ways to treat diseases, from neurodegenerative disorders to cancer.
Organocatalysts consisting of organic compounds without metal elements are receiving much attention as next generation catalysts in the hope of reducing environmental burden and coping with exhaustion/rising prices of rare metals.
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.
