DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

The remaining positions are occupied by carbon atoms, forming the backbone of important nucleobases in DNA and RNA. (Image: Public Domain) Types of Pyrimidines in Nucleic Acids There are three types ...

A new study conducted by researchers from the Institute of Modern Physics of the Chinese Academy of Sciences  has uncovered a key mechanism involving Intermolecular Coulombic Decay in aqueous ...

thymine and uracil are all pyrimidines: single rings. To maintain its orderly structure, single rings on one strand can only bond with double rings on the other. This keeps the DNA molecule in the ...

This image illustrates the chemical structures of the five main nucleobases found in DNA and RNA. The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine ...

Rather, DNA was first identified in the late 1860s ... In other words, the total amount of purines (A + G) and the total amount of pyrimidines (C + T) are usually nearly equal.

To multiply rapidly, cancer cells need to quickly manufacture DNA and RNA, which requires sufficient quantities of purines and pyrimidines. Upon analyzing the levels of 3,000 genes in a T cell ...
