The insertion of a human DNA fragment into a bacterial cell might make it possible for?

Question

1) the bacterial cell to produce a human protein

2) the cloning of the human that donated that DNA fragment

3) humans to become immune to an infection by this type of bacteria

4) the cloning of this type of bacteria

Answer 1

1) the bacterial cell to produce a human protein

Answer 2

The first one, that's how they produce insulin, by inserting part of a human gene (the insulin bit) into the bacteria's ring of DNA, (called the plasmid) and the bacteria is then therefore capable of producing human insulin.
