Several stages in the production of human insulin by genetic modification are given below. 1 insertion of the human insulin gene DNA into a bacterial plasmid that has been cut 2 bacteria containing recombinant plasmids multiply and produce human insulin 3 human insulin gene DNA is isolated using restriction enzymes 4 recombinant plasmids are inserted into bacteria What is the correct order of these processes in genetic modification?
- A$1 \rightarrow 3 \rightarrow 2 \rightarrow 4$
- B$1 \rightarrow 4 \rightarrow 3 \rightarrow 2$
- C$3 \rightarrow 1 \rightarrow 4 \rightarrow 2$
- D$3 \rightarrow 2 \rightarrow 1 \rightarrow 4$
