DNA Technology

Separation of DNA using electric current is called.....?

• Gel Electrophoresis
• Chromosome painting
• polymerage chain reaction
• Restrictive Enzyme Sorting 

What is the enzymatic function of restriction enzymes?

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

What enzyme forms covalent bonds between restriction fragments?

• DNA primase
• DNA helicase
• DNA ligase
• DNA polymerase

What is the most logical sequence of steps for splicing foreign DNA into a plasmid and inserting the plasmid into bacterium?
I) Transform bacteria with recombinant DNA molecule.
II) Cut the plasmid DNA using restriction enzymes.
III) Extract plasmid DNA from bacterial cells.
IV) Hydrogen-bond the plasmid DNA to non-plasmid DNA fragments.
V) Use ligase to seal plasmid DNA to non-plasmid DNA
