Define Genetic Engineering

Process where
_________________________

is split into
_________________

and new DNA pieces are
inserted



___________________________________

enzymes cut DNA at certain places



_____________________

are then used to insert
____________________

splices



Now referred to as
_____________________________

DNA or
________________

Applications of recombinant DNA

_____________________________
: used to reduce frost damage to crops, break down pollutants,
produce hormones and antibioti
cs

_____________________________
: resistant to herbicides, increase protein content in grains

_____________________________
: cloning of endangered species, replacement of genes which cause
disorders

Describe DNA fingerprinting



Samples of
__________________

is exposed to
______________________________

enzyme
which cuts
DNA

into pieces
.



________________________

is loaded into a
______________
and run through an
electrophoresis machine



Since
_________________

is cut at certain sequences, each piece is a differ
ent length and
weight



Pieces that are
________________________
stay at the
____________

of the gel,
________________________

will “run” to the
__________________________.



Every person is genetically different, so DNA
____________________________

are differe
nt

DNA fingerprinting applications



Can be used to identify or eliminate
___________________________
when genetic material has
been collected at a crime scene



Can be used to determine
_________________________
of a child, or establish other family
___________
_____________________________.



Can be used to identify a

___________________________________

person

Describe karyotyping



_____________________________________

of
_____________________________

are taken
from a
________________________
sample, cut out and mat
ched up in pairs
.



Humans have
______________

pairs of chromosomes
.



Describe karyotyping Continued



_____________________________

can be used to determine if genetic disorder is present
.
If
too many are present can indicate
________________________
syndrome
.



If some are missing can indicate
_____________________

syndrome
.

Gene therapy



_____________________________
of normal gene into human cell to correct genetic disorders



Being used now to treat
______________________________________, Turner’s syndrome,
Klin
efelter’s Syndrome.

2. Gene
_____________________________

Involves the insertion of normal genes in the place of genes
whi
ch control genetic disorders.


a. cloning b. mutation c.therapy


3.
DNA fingerprinting works because everyone’s DNA is different except for
______________________.


a. fraternal twins b. identical twins


4.
The structure of DNA was discove
red by
_________________________________.


a. Watson

& Crick b. Wilson & Crockett
c. Schleiden & Schwann


5.
DNA gels can be used for
_______________________________________.
