Explore 40 years of PCR history, from Kary Mullis’s invention story to the rise of digital PCR and how it revolutionized ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Researchers revealed a CRISPR system that activates gene expression rather than cutting DNA, using RNA-guided targeting. The discovery opens new possibilities for CRISPR therapies.

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries the information contained within DNA to the ribosomes, where the genetic information is synthesized into ...
