What causes DNA to make a bone cell instead of a stomach cell?
the muscle cell has more DNA
the chromosomal arrangement determines it
DNA gets transcribed and translated to make the cell
they have different DNA in them
When you use a gel electrophoresis machine to identify a suspect, what is this process?
bacterial transformation
DNA fingerprinting
gene therapy
cloning
If someone left a hair strand at a crime scene, how could we use it to identify the criminal?
testing it for protein
compare it to the hair color of the victim
testing it for lipids
doing DNA analysis on the hair strand
Why is DNA fingerprinting a reliable method?
DNA sequences are unique making identification easy
DNA is the same in most people so it helps put people in groups
DNA can show the weight and height of someone
DNA lasts forever and can't be destroyed
How have GMOs in agriculture helped the environment?
it has required less water for animals
its made us use less natural resources
it has reduced diversity
it has reduced use of toxic herbicides
Match the person to the blood sample.

What do restriction enzymes do?
allows DNA to have an electrical charge
it makes testing go faster
it cuts DNA strands at different lengths
it reads the genetic code and processes it
What does the agarose gel do in the gel electrophoresis machine?
it allows different sized DNA to band at different rates
it gives off a positive charge, allowing DNA to move fast
it cuts DNA at different sizes so that it can go through
it makes the DNA turn blue, purple, or red to read it
True or False: Longer DNA fragments run through quicker!
True
False
Why are stem cells used?
They make it easier to analyze DNA.
They help cells clone themselves.
They can become any type of cell.
They can alter all of your DNA.
How can we identify individuals?
the shape of their DNA molecule
the size of their chromosomes
the sequence of the their nucleotides
the number of chromosomes each person has
If everyone has about 99% of the same DNA, how does gel electrophoresis identify individuals?
The small segments of DNA vary & are specific
DNA turns different colors in the tray
DNA reflects differently in the light
There is a genetic alphabet that lights up in the gel.
A crop has been developed using a gene from a plasmid that makes it toxic for pests to eat. Which process made this?
stem cells
gel electrophoresis
bacterial transformation
cloning
What is a plasmid used for?
to introduce new DNA into bacteria
to remove a segment of a gene
to activate the restriction enzyme
to cut DNA in a specific spot
If a new gene starts to show up in some of the bacteria after a transformation, that means:
the transformation failed
the transformation was successful
there was a mutation in the gene
the bacteria couldn't pass it on
When inserted genes from one organism to another start to produce a protein & trait, this is called:
recombinant DNA
transgenia
plasmids
electrophoresis
A liger (mix between a lion and tiger) gets DNA from 2 organisms. It is a:
clone
plasmid
transgenic organism
differentiated stem cell
Genetic engineering has helped those with Diabetes. How?
It allows them to inject themselves with smaller needles.
It has cured all types of diabetes.
It allows them to inject themselves with human insulin.
It allows them to use insulin and then be cured.
True or False: The Human Genome Project has mapped ALL of the genes within our bodies!
true
false
Which disorder has the Human Genome Project helped by identifying the faulty gene and providing treatments?
Down syndrome
Pneumonia
Cystic Fibrosis
Whooping Cough
What has helped provide the diagnosis and treatment of disorders?
organ transplants
Human Genome Project
cell differentiation
Vaccines
How is gene therapy beneficial?
It has mapped all genes.
It can correct disorders & insert healthy genes.
It provides therapy to patients with mental health issues.
It takes genes and replaces and changes someone's DNA.
Cloned crops can be a problem because:
They require more water and nutrients.
They prevent pests from eating them.
It adds diversity to the crops.
They could pass a disease on to all crops.
The Human Genome Project is helpful because:
we can now better understand genetic diseases
stem cells are used to regrow organs
we can now use animal DNA in humans
it allows us to identify people
If a type of bacteria has undergone bacterial transformation, what can we expect to see?
they reproduce quicker than they did before
they become a brand new species
they will express the new protein/trait
they will have more chromosomes than normal bacteria
True or False: A benefit to stem cell research is that it has the potential to cure and treat diseases.
true
false
