The diagram is used to

• make a clone
• run gel electrophoresis 
• find RNA 
• make DNA mutations

What is the enzymatic function of restriction enzymes?

• To add new nucleotides to a growing strand of DNA.
• To join nucleotides during replication.
• To join nucleotides during transcription.
• To cleave/break nucleic acids at specific sites.

In order to insert a human gene into plasmid, both must 

• code for the same gene product.
• be cut by the same restriction enzyme.
• originate from the same type of cell.
• have identical DNA sequences.

What is the most logical sequence of steps for splicing foreign DNA into a plasmid and inserting the plasmid into a bacterium?
I) Grow transgenic bacteria.
II) Cut the plasmid DNA using restriction enzymes.
III) Extract plasmid DNA from a bacterial cell.
IV) Create recombinant DNA.
V) Combine the gene of interest to the plasmid, creating recombinant DNA
