RNA can fold into more complex configurations than scientists thought, raising questions about how important these 3D ...

Despite being made from a relatively simple set of building blocks, ribonucleic acid (RNA) has a broad array of complex responsibilities. From providing structure to carrying the instructions for ...

In most modern cells, DNA stores the genetic blueprint, and relies on proteins to replicate, repair and build from those ...

Caltech researchers have identified a novel chemical reaction that could explain the formation of the building blocks of DNA and RNA, the molecules that encode all of life's functions. The work is an ...

Ask a friend what DNA is and, chances are, they have a general idea. Seventy years after scientists discovered the two-stranded helix, DNA (deoxyribonucleic acid) is widely understood as the keeper of ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study uncovers how amino acids could have linked with RNA under early Earth conditions, shedding light on the origin of life ...

More than four billion years ago, Earth was a very different place. Pools of water froze and thawed in cycles, minerals shaped reactions, and molecules bumped into each other by chance. Out of this ...
