Quizplus · Accepted Answer

Gene mutations can be caused by environmental agents such as radiation, chemicals, and viruses. They can also occur spontaneously due to errors during DNA replication or repair. Not all mutations are damaging, some can be neutral or even beneficial depending on their effects on the organism's phenotype. Additionally, mutations can occur in both prokaryotes and eukaryotes.
