Some of the elements necessary to support life on Earth are widely known - oxygen, carbon and water, to name a few. Just as important in the existence of life as any other component is the presence of ...

Adenine was first discovered in 1885 by the German physiologist Albrecht Kossel. He isolated adenine from the pancreas of oxen and named it "adenine" derived from the Greek word "aden," meaning gland.

A sample collected by the Hayabusa 2 spacecraft from the spinning top-like asteroid contained the nucleobases adenine, ...

Physicists have shown that one of the building blocks of DNA and RNA, adenine, has an unexpectedly variable range of ionization energies along its reaction pathways. Early Earth's atmosphere provided ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

Urine levels of adenine, a metabolite produced in the kidney, are predictive and a causative biomarker of looming progressive kidney failure in patients with diabetes, a finding that could lead to ...

Many diseases, such as sickle-cell anemia, are caused by single-base mutations in genomic DNA. Scientists have long searched for methods to correct such single-base mutations, with hopes of possibly ...

Cytosine bases here and there in DNA are famously decorated with methyl groups, chemical modifications that silence genes so that specific cells express only certain, appropriate DNA sequences. This ...
