Inside Synchronization Mode, Young-Joon was examining the body of Mimi, the Cas9 baby who was the very first genetically modified baby in the world. Cas9 and RNA fragments wrapped in exosomes were gradually being injected into the lymph nodes and bone marrow in five hundred microliter volumes of injection fluid. There were going to be seventy-two injections over her entire body, and they had to do this again in two days.0

‘It’s a lot for a newborn baby’s body to take, but…’0

There was no better way. The only way to normalize the CCR5 gene in this baby with a compromised immune system was this.0

Rosaline focused on the lymph nodes under her chest. The exosomes were binding to the membranes of the cells in the lymph nodes, injecting Cas9 and the RNA complex into the cell.0

‘Using exosomes was a good choice.’0

Exosomes were essentially a kind of written communication between cells. They were particularly common in cancer cells, and in this case, Young-Joon used them to safely introduce Cas9 into the cell without disrupting the structure.0

The Cas9, which was now inside the body, searched through all three billion bases of DNA as guided by the RNA and found CCR5 in a matter of seconds.0

Crackle!0

Phosphoric acid and sparks flew as the phosphate backbone of the DNA molecule broke. Now, Synchronization Mode allowed Young-Joon...0
