A molecule created by combining DNA that was cut with restriction enzymes from two different organisms
a plasmid.
a polyploid.
a hybrid organism.
recombinant DNA.
A gene is a section of DNA that contains the instructions for making what?
chromosomes
carbohydrates
proteins
lipids
In which ways can genetic engineering can improve crops
Make them pest or drought resistant
Make them more nutritious
Make them produce more food
All answers are correct
Which term refers to a breeder choosing which dogs he or she mates based on desired traits?
natural selection
selective breeding
genetic engineering
genetic transformation
Which best explains why muscle cells function differently from white blood cells in the same person?
Muscle cells are produced by the brain, but white blood cells are produced by the heart.
Different genes are activated in muscle cells than in white blood cells.
Muscles cells and white blood cells in the same person contain different DNA.
A mutation occurs during the development of muscle cells but not in white blood cells.
Which technology below would probably be the most important to a person who had diabetes and had to take insulin every day?
using recombinant DNA to produce human hormones from bacteria
testing parents for genetic disorders before they have children
engineering fruits and vegetables that resist insects and other pests
developing ways to identify criminals through DNA fingerprinting
What type of macromolecule are restriction enzymes (and all biological catalysts)?
nucleic acid
carbohydrate
protein
lipid
Which of the following jobs is NOT done using restriction enzymes?
Cut DNA at a specific site
Can be used to isolate a gene of interest
Can be used to cut open a bacterial plasmid DNA ring
Speeds up digestion
Clones have the exact same:
Personalities
Physical appearances
Intelligence levels
Genetic material
The purpose of selective breeding is to
Get bigger organisms
create recombinant DNA
create organisms with desirable traits
create transgenic organisms
What is the name of the process described below?
1. The nucleus is removed from an unfertilised egg cell and is replaced with a nucleus that has been removed from a skin cell.
2. The new cell is given an electric shock which causes it to start dividing.
3. The embryo is inserted into a host mother.
4. The offspring will be genetically identical to the adult skin cell.
Sexual reproduction
Somatic (body) cell cloning
Selective breeding
Natural twinning
This laboratory procedure is known as
cloning
gel electrophoresis
chromatography
genetic engineering
In preparation for an electrophoresis procedure, enzymes are added to DNA in order to
convert the DNA into gel
cut the DNA into fragments
change the color of the DNA
produce longer sections of DNA
The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel
electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?
They have the correct child, because her genetic information is identical to that of the father.
They have the wrong child, because her genetic information does not match that of either parent.
They have the correct child, because her genetic information came from both parents.
They have the wrong child, because her genetic information matches only that of the mother.
What is this technique an example of?
chromatography
gel electrophoresis
selective breeding
genetic engineering
A technique that can be used to compare the DNA of two or more plants is
cloning
chromatography
staining
gel electrophoresis
Gel electrophoresis is used to separate DNA fragments on the basis of which property?
size
color
functions
chromosomes
. Which process is illustrated in the diagram below?
chromatography
direct harvesting
meiosis
genetic engineering
The arrows in the diagram below indicate the development of four different varieties of vegetable plants from wild mustard.Each of these varieties was most likely produced as a result of
asexual reproduction in the wild for many years
changes in light availability
competition between plants
selective breeding over many generations
Why do the fragments of DNA in gel electrophoresis travel away from the negative electrode (charge)?
DNA is negatively charged so attracted to the positive end of the unit
DNA is positively charged to attracted to the negative end of the unit
the agarose gel in negatively charged
the agarose gel is positively charged
