For millions of years, bacteria and viruses have been locked in an evolutionary arms race. Viruses evolving new mechanisms to evade CRISPR, and CRISPR evolving to find different ways of preventing re-infection. CRISPR Cas9 is one such permutation.
CRISPR Cas9 printed in full-color sandstone. RNA is colored red, DNA colored Yellow and Green. The subtle color variations in the CRISPR are associated with its atomic temperature. 3D print of CRISPR Cas9 created from PDB ID: 5AXW.
