"If you consider the four major building blocks of life as nucleic acid bases, amino acids, fatty acids, and carbohydrates, we have demonstrated that some fatty acids can form micelles and ...

Samples from NASA’s OSIRIS-REx mission show the asteroid Bennu had organic molecules and minerals and possibly salty water and other life ingredients.

For years, researchers described DNA and RNA as linear chains of four building blocks—the nucleotides A, G, C, and T for DNA; and A, G, C, and U for RNA. But these information molecules are much more ...

"The detection of these key building blocks of life in the Bennu samples supports the theory that asteroids and their fragments seeded the early Earth with the raw ingredients that led to the ...

Purine nucleotides are essential for cell growth and function as they serve as nucleic acid building blocks, signaling molecules, and energy carriers. Treatments that inhibit their synthesis offer a ...
