Two DNA Molecules Should Repel. Instead, They “Zip” Together
AI KEY TAKEAWAYS (TL;DR)
- Scientists have revealed how tiny metal ions help DNA molecules overcome electrical repulsion and “zip” together with striking precision
- DNA molecules carry the same negative charge, so they would normally be expected to push apart
- Inside living cells, however, DNA must sometimes come together for processes such as genetic recombination, gene silencing and cancer development
Why it matters: Highlights progress and positive advancements shaping a better world.
