DNA’s vulnerability to sunlight may explain the complex origins of intelligent life
Thymine suffers more UV damage than uracil in lab tests, but its damage pathways could help explain its place in DNA.
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 blueprints. At the same time, proteins require instructions from DNA to be made ...

New DNA findings may explain how octopuses evolved complex brains
A comparative genome study and squid embryo experiment explore how folded DNA may shape cephalopod gene regulation.
Scientists have uncovered an unexpected danger lurking inside cells: too much RNA can damage the structures responsible for ...
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 ...
