Answer 19

@nincompoop We can't remember and say everything we always want to.

@abb0t I don't get your comment about some one "come at" you. I don't see anyone doing so. Also, it may not be a simple question. If the OP is in high school or middle school, the answer the teacher wants could very well be something about all cells needing DNA to be protected from harm. If it is a university class, the answer could very well be that not all cells have a nucleus.
