Young-Joon gathered the genes that made up the end of the anthracis cilia and put it in an E. coli plasmid. They were put into BL21, a strain of bacteria, then grown in LB broth. Then, all the bacteria were killed by sonication, and it was purified using a histidine tag that was attached to a piece of the cilia.2

‘Done.’0

Young-Joon proceeded with care and caution as if he was building an elaborate Lego sculpture. He attached DNase, a substance that destroyed DNA, to streptavidin, then added it to the cilia to anthracis with biotin. The scientists under the University of Kinshasa and Michelle were closely observing what Young-Joon was doing. All he was doing was mixing, measuring, and collecting solutions that were less than a milliliter. It seemed like nothing much to the human eye, but important things were happening in the microworld. The scientists followed along closely as they took notes.0

“It’s done,” Young-Joon said.0

“The treatment is done?” Nazir asked.0

“Yes. We’re ready for the pilot experiment. Let’s take the samples you made and go to the lab.”0

Young-Joon and thirty other scientists left the biology lab at the University of Kinshasa and drove forty minutes to...0
