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 ...

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 ...

In Biology 101, we learn that RNA is a single, ribbon-like strand of base pairs that is copied from our DNA and then read like a recipe to build a protein. But there's more to the story. Some RNA ...

Within each cell, there is a constant struggle between life-sustaining molecules and molecules that could hasten its demise.

Researchers have now uncovered the 3D structure of the RNA enzyme SAMURI. Their study provides insights into the development of ribozymes and the evolution of catalytically active RNA. Researchers led ...

Cells contain a blueprint in the form of DNA that dictates what they can make. This blueprint is converted into a message ...

Researchers used cryo-EM to study how the HIV enzyme integrase arranges in 3D to slip its DNA into the host genome and pack ...
