Research Unveils RNA-Based Life's Genome Repair Origins
✦AI Summary
Researchers have engineered a ribozyme capable of repairing broken RNA strands, supporting the 'RNA World' hypothesis regarding the origins of life. This discovery suggests that RNA could have managed its own genetic preservation without the need for proteins.
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 in the first place.
