Mutation of __________ can profoundly modify an organism.

Question

Quizplus · Accepted Answer

A regulatory gene controls the expression of other genes, so a mutation in this gene can have a cascading effect on multiple biological processes. Mutations in other parts of DNA or chromosomes can also have significant impacts, but they may not necessarily affect as many aspects of an organism as a regulatory gene mutation would. The nucleus of the cell is responsible for housing DNA and chromosomes, so a mutation of the nucleus itself is not possible.
