Still, even in bacteria, with their smaller genomes, DNA replication involves an incredibly sophisticated, highly coordinated series of molecular events.

DNA Replication: Within the nucleus of every cell are long strings of DNA, the code that holds all the information needed to make and control every cell within a living organism.

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes ...

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

In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature biosensors and drug-delivery containers.
