CRISPR-Cas9 has revolutionized biology. But how does it actually work? Think of it as a "find and replace" tool for DNA.
The Components
The system consists of two main parts:
- Cas9 Enzyme: The "molecular scissors" that cut the DNA.
- Guide RNA (gRNA): The "GPS" that directs Cas9 to the specific location in the genome.
Applications
From correcting genetic defects to treating cancer and improving crops, the potential applications are limitless.
