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 ...

Polymers are made of monomers, and in DNA, these monomers are called nucleotides or nucleobases. The enzymes that handle DNA molecules are often called "polymerases," but the -ase suffix denotes ...

All five nucleobases that make up DNA and RNA have now been detected in meteorite samples, according to a study published yesterday (April 26) in Nature Communications. The work used recently ...

Focused on 2-thiouracil — a molecule related to DNA building blocks known as nucleobases — the study revealed structural ...

"We investigated the molecule 2-thiouracil, which belongs to a group of pharmaceutically active substances based on certain DNA building blocks, the nucleobases," says the study's last author ...

All life on Earth is made of complex organic molecules. These include amino acids that make up proteins, nucleobases in DNA and carbohydrates like sugars. Scientists doubt that the early Earth had ...
