Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

DNA holds our genetic blueprints, but its cousin, RNA, conducts our daily lives I n 1957, just four years after Francis Crick ...

After decades of speculation, researchers have demonstrated that a classical DNA repair enzyme also binds to RNA, affecting blood cell development. The DNA-dependent protein kinase, otherwise known as ...

Despite being made from a relatively simple set of building blocks, ribonucleic acid (RNA) has a broad array of complex ...

Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or “ribozyme,” that carries out a fundamental reaction required to make new ...

The origin of life continues to remain a matter of debate. The ribonucleic acid (RNA) world hypothesis proposes that 'ribozymes' which store genetic information and possess catalytic functions may ...

The development of DNA-/RNA-based drugs, like COVID-19 vaccines, is exploding. Current methods are costly, but researchers are finding effective and inexpensive method for producing stable, modified ...

Francesca Storici consults at Tessera Therapeutics. She has received funding from the National Institutes of Health and the National Science Foundation. Your DNA is continually damaged by sources both ...
