What is the correct sequence in creating a DNA profile?

A) Collect sample $\rightarrow$ extract DNA $\rightarrow$ PCR to amplify STRs $\rightarrow$ gel electrophoresis $\rightarrow$ analyze gel
B) Collect sample $\rightarrow$ extract DNA $\rightarrow$ gel electrophoresis $\rightarrow$ PCR to amplify STRs $\rightarrow$ analyze gel
C) Collect sample $\rightarrow$ gel electrophoresis $\rightarrow$ extract DNA $\rightarrow$ PCR to amplify STRs $\rightarrow$ gel electrophoresis again $\rightarrow$ analyze gel
D) Collect sample $\rightarrow$ PCR to amplify sample $\rightarrow$ gel electrophoresis $\rightarrow$ extract DNA $\rightarrow$ gel electrophoresis again $\rightarrow$ analyze gel
E) PCR to amplify sample $\rightarrow$ extract DNA $\rightarrow$ gel electrophoresis $\rightarrow$ analyze gel
