Questions & Answers

Q: What did He Jiankui do with CRISPR?

He used CRISPR to knock out the ccr5 gene in human embryos, with the aim of protecting the twin girls from HIV infection.

Q: How did the scientific community react to He Jiankui's announcement?

The scientific community reacted with shock and condemnation, criticizing the ethical implications and the lack of proper oversight and regulation.

Q: What was the motive behind He Jiankui's gene editing experiment?

He Jiankui claimed that his motive was noble, as he wanted to protect the twin girls from the risk of HIV infection due to their father being HIV positive.

Q: Did the scientific community have prior knowledge of He Jiankui's work?

There was limited knowledge within the scientific community about He Jiankui's specific actions, as he was working in relative secrecy in China. Some colleagues, like William Harlan, the bioethicist and research scholar, had knowledge but did not fully comprehend the extent of his experimentation.
