It can be harmful to the organism that carries itپاسخ درست
It can have no noticeable effect at allپاسخ درست
Every mutation shows up as a visible change
It can be beneficial in the organism's surroundingsپاسخ درست

توضیح

Assuming that harm always follows treats every change to a long instruction as damage, when many changes leave the protein and the organism working exactly as before.
