This is from the BBC, Alyssa's revolutionary cancer treatment
In Alyssa's therapy, each of the base edits involved breaking a section of genetic code so it no longer worked.
I did not quite understand the logic in this sentence. I understand that they broke a section of the genetic code because it was no longer working. In other words, it had already stopped working, so, they decided to remove that section.
But if you read ".....so it no longer worked.",** it means that "they removed that section in order for it not to work any more.", which would not make sense.
So, I think it should be "....because it no longer worked", NOT "....so it no longer worked".
Do you think so?
