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?

Purines Adenine (A): Adenine is one of the two purine bases found in both DNA and RNA. It pairs with thymine (T) in DNA and uracil (U) in RNA through hydrogen bonding. Guanine (G): Guanine is the ...

In nucleosides, purine or pyrimidine bases are connected to the C-1 position of the sugar through the nitrogen on the ring, forming various nucleosides and their derivatives. This is a valuable method ...

Purines and pyrimidines are the two different kinds of nucleobases in DNA and RNA. Adenine (A) and guanine (G) are purines and cytosine (C), thymine (T) and uracil (U) are pyrimidines.

KELEMEN, S., DEGENS, E. Rapid Column Chromatography of Purine and Pyrimidine Bases on ‘Ectaola’ Cellulose at Room Temperature and Elevated Pressure. Nature 211, 857–859 (1966). https://doi ...

The scientists show how purines and pyrimidines can form from a common precursor molecule that could have existed before life on Earth began. They find 8-oxo-purine shares underlying similarities ...

A solution to this problem has remained elusive for more than 50 years.” The team demonstrated how purines and pyrimidine nucleotides can both be assembled on the same sugar scaffold to form molecules ...

Two complementary strands of DNA form a double helix because the purine bases adenine (A) and guanine (G) form specific pairs with the pyrimidine bases thymine (T) and cytosine (C), attaching to ...

This article outlines the biological significance of one of the most important heterocycles, the pyrimidine. An attempt has been made to cover most of the physiologically as well as medicinally ...
