1.c 2.A 3.c 4. D three might be wrong
2) was d 3) was d
sorry i dont remember all that stuff
I just took the quiz and these replies are mainly wrong, here are the 100% correct ones: 1. Frameshift Mutation 2. All of the above are correct 3. Deletirious 4. Translocation
NSchool your my ROCKSTAR
I agree with JSUTTON. You are awesome NSchool.
These answer vary as they can be switched around.
4 is b
4 is B!
The correct answers are 1. D 2. D 3. D 4. B
