The basic molecules that make up all living things have a predetermined chirality or "handedness," similar to the way people are right or left handed. This chirality has a profound influence on the ...

In a system with self-replicating molecules -previously shown to have the capability to grow, divide and evolve - chemists from the University of Groningen have now discovered catalytic capabilities ...

RNA molecules are essential for cellular information transfer and gene regulation, and RNAs have been implicated in many human diseases. Messenger and non-coding RNAs contain highly structured ...

In an experiment that mimics astrophysical conditions, with cryogenic temperatures in an ultrahigh vacuum, scientists used an electron gun to irradiate thin sheets of ice covered in basic molecules of ...

ARGONNE, Ill. (December 1, 2008) — The basic molecules that make up all living things have a predetermined chirality or "handedness," similar to the way people are right- or left-handed. This ...

All the basic structures in animals, plants as well as microorganisms are made up primarily of three basic classes of molecules: These are important for life and metabolism helps organisms in breaking ...

Surely but slowly, scientists are learning the structure of the basic molecules of life. They are gradually discovering how those molecules perform their exquisitely delicate and extraordinarily ...

Life on Earth relies on molecular building blocks to make DNA and proteins. Scientists have long wondered how prevalent these precursors were at the birth of our solar system. A sample of dust and ...

University researchers recently acquired molecule products from bacteria through activating “silent genes.” The molecules have potential use for drugs but need further research. Silent genes are genes ...
