Successful treatments using stem cells MUST use embryonic stem cells
True
False
Selective breeding has been recently developed to produce different types of plants.
True
False
The goal of gene therapy is to replace a faulty gene with a functioning one.
True
False
When embryonic stem cells are harvested, it kills the embryo.
True
False
Therapeutic cloning makes spare parts to help sick people.
True
False
Copy cat is the only animal to be cloned.
True
False
Any food that we eat contains DNA if that food came from a living thing.
True
False
Breeders have used the process of selective breeding to:
produce desired traits
produce transgenic oganisms
get less offspring
get more offspring
Breeding 2 very similar organisms to get some desired trait in the offspring.
artificial cloning
twinning
inbreeding
cross breeding
A cell that has become differentiated:
can produce any type of cell
has become specialized to perform a particular function
can only be plant cells
are reproductive cells
Mimi the mouse was cloned from:
the DNA molecules in her egg cell
the DNA in a sperm cell
the egg cell of a different mouse
a somatic (body) cell
Somatic cell nuclear transfer is the process used to:
clone an organism
selectively breed organisms
DNA fingerprint someone
create a GMO
Which types of cells are used to produce a clone?
a somatic (body) cell only
an egg cell only
egg and sperm cells united together
a somatic cell and an egg cell
Making a permanent change in the DNA of an organism is:
genetic engineering
selective breeding
inbreeding
hybridization
DNA that is produced by combining DNA from 2 different sources is called:
a hybrid
mutation
recombinant DNA
a polyploid
What is the first step in producing a transgenic organism?
use restriction enzymes to cut out the desired piece of DNA
insert the gene into the DNA of a different cell
clone the cell containing the inserted gene
extract the substance produced by the transgenic organism
A ______________ is a circular piece of DNA that is often used as a vector in genetic engineering.
recombinant
plasmid
enzyme
stem cell
A restriction enzyme is a protein that:
creates a plasmid in a bacteria
snips a piece of DNA out of a larger molecule
helps join transgenic DNA
forms many products from recombinant DNA
This drug has been produced with the help of genetic engineering.
insulin
adrenaline
myosin
glucose
What is DNA fingerprinting used for?
treat human disease
clone valuable organisms
identify criminals
produce drugs for humans
Matching DNA fingerprints tells us that:
the DNA fragments were the same size
there was the same amount of DNA
there were identical DNA molecules
all are true
Why is DNA fingerprinting thought to be so exact in identifying a person?
no 2 people have identical DNA (except identical twins)
most people have repeated DNA segments
most genes are dominant
DNA fingerprints are the same for everyone
Which crop in the United States is almost ALL GMO?
rye grass
soybeans
grapes
lobster
For what reason do plant geneticists create GMO plants?
to increase offspring produced
to create resistance to disease
to improve nutrition
all of them are correct
Crossing very different varieties of organisms to produce a more vigorous offspring is called:
hybrid vigor
cloning
inbreeding
hybridization
