RECENTLY Donovan and Woodhouse 1 advanced a speculation on the nature of the chemical structure which is the essence of the malignant cell. Their idea is the formulation of a molecule in the ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

DNA—the biological information-storage unit and the mechanism by which traits are passed on from generation to generation—is more than just an essential molecule of life. In the chemical sense, the ...

Nucleotides are the fundamental units that make up the genetic material of all living organisms. They are the building blocks of DNA and RNA, which store and transmit genetic information. Nucleotides ...

Guanine quadruplexes (G-quadruplexes or G4s) are unusual nucleic acid structures with distinct biological and chemical functions. They have occupied significant attention in the nucleic acid world ...

A vascular dilatation in the aorta can be life-threatening if it bursts. These so-called aortic aneurysms typically form in the same sites of the large blood vessel: either on the upper arch or in the ...
