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 purine structure consists of a pyrimidine ring (positions 1 to 6 ... and the synthesis of complex molecules. GTP is another purine nucleotide that plays a crucial role in cellular signaling and ...

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 ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...

The double helical structure is made of two strands consisting of deoxyribose and phosphate and is held together by bonds between purine and pyrimidine bases which project inward from two chains and ...

4,5 Across all study populations, pyrimidine nucleoside and/or nucleotide therapy was generally well tolerated. 1,2,3 TK2d is an ultra-rare, life-threatening, genetic mitochondrial disease with no ...
