Study Guide
 Biotechnology-forensics
 Genetically
Modified Organisms; also
called transgenic organisms; contain
recombinant DNA
 Producing
organisms that have
desirable characteristics, such as
higher crop yields
 DNA
produced by combining DNA
from different sources
 Inserting
functional genes into the
cells that need them, replacing
nonfunctional genes
 Enzymes
cut DNA
produced by bacteria used to
 The
fact that no two people, except
identical twins, have exactly the same
DNA; the use of STRs that do differ
from person to person
 the
cell integrates foreign DNA into
one of its chromosomes-recombinant
DNA
 Engineering
bacteria that produce
human insulin or human growth
hormone.
 Particular
sequence of bases where
restriction enzymes cut
 Gel
electrophoresis
 By
size
 because
they easily and readily accept
foreign DNA to transform bacteria
 The
source of a clone’s DNA is a single
cell taken from an adult individual.
 Crossing
organisms with similar
characteristics. Ex. A poodle with a
poodle
 Crossing
organisms with different
characteristics; ex.> to create animals
that have the characteristics of both
species, some people have bred
buffalo and cattle together.
 cloning
 to
make sure that all of the DNA in the
clone was from a single sheep.
 Sheep
A
 The
lamb
 Sheep
B
 Sheep
A and the lamb are genetically
identical, because sheep A provided
the nuclear DNA for the cell.
 Gel
electrophoresis
 The
restriction enzyme is cutting the
DNA into fragments.
 The
bands consist of DNA, which is
negatively charged.

DNA fragments.
 group
D because they consist of
smaller DNA fragments.
 No,
the 3 DNA samples can’t be from
the same person because they would
have produced the same pattern
