Answer 1

9.Barbara Mc clintock was the first to study transposable elements .

10. its C , repressible operon which will turn off the operon .

11.its D , cancer is only caused by mutations we inherit from parents , this is incorrects as it is caused due to many reasons just not from mutations we inherit from our parents.

12. it's A genetic engineering . as the genes are recombined and engineered to produce new combination it is called as genetic engineering.
