Plus it was different mutagens was it not? But I dont actually know if that would be a factor. I've only done High School Biology.

The first one was irreversible...his genes were altered and permanent from the first mutagen.. The 2nd one was like a disease in his case. DNA has the capability to restore and repair itself if it makes a mistake or something is introduced to it such as mutagens. But in Donnie's case, his DNA is a combination of the turtle DNA and whatever was in the original mutagen.
