Tool/Process
What Is It?
How Is It Useful?
Restriction Enzymes
Cuts (cleaves) DNA at
specific sequences to
make fragments w/
sticky or blunt ends
Gel Electrophoresis/
Uses an electrical current Used to study individual
to separate DNA
fragments or to identify
fragments by size
suspects, bodies, or
biological parents
DNA Fingerprinting
Combines existing DNA
with a fragment from
Recombinant DNA Technology another source
Allows genes to be
removed or added.
Used to make DNA
fingerprints.
Used to study individual
genes, genetically
engineer organisms, or
treat diseases.
Gene Cloning
Makes many copies of
recombinant DNA
containing individual
genes
DNA Sequencing
Determines the unknown Allows DNA to be
sequence of DNA
studied so that mistakes,
molecules
mutations, or genes can
be identified.
PCR
(Polymerase Chain Reaction)
Transgenic Animals
Transgenic Plants
Transgenic Bacteria
Used to study genes or
genetically engineer
organisms.
Makes many copies of an Used for forensic
entire region of DNA
investigation and in
medical testing.
Animals that have
Used to study diseases
received DNA from some and ways to treat them,
other organism
to improve food supply,
disease resistance, and
human health.
Plants that have received Creates plants that are
DNA from some other
disease/insect resistant,
organism
faster growing, more
nutritious, non-allergic
Bacteria that have
Used to make insulin &
received DNA from some other hormones, and to
other organism
clean up oil spills, etc.
