question 13
what are the main steps of pcr?
1 primer annealing at 55 to 65 oc
2 after one cycle, dna molecules are doubled
3 denaturation of the dna at 94 to 98 oc
4 primer extension at 72 oc

Explanation:

Dolly was the first cloned mammal. Her cloning demonstrated that it was possible to clone animals. This led to further research and the idea of cloning other animals. Option b is about natural selection which is not related to cloning. Option c is about gene crossing which is not relevant here. Option d is incorrect as Dolly's cloning opened the door to cloning other animals, not closed it.

Answer:

a. It opened the door to the idea of cloning other animals
