In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in ...

Animation of DNA’s knot-like i-motif structure the team mapped in 50,000 locations in the human genome, concentrated in key functional areas including regions that control gene activity ...

DNA replication is a powerful testimony to the complexity and elegance of life itself. Each time a cell divides, it’s tasked with copying around 3 billion nucleotides—an astonishing feat that ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

Technology DNA nanobots can exponentially self-replicate Tiny machines made from strands of DNA can build copies of themselves, leading to exponential replication.
