 Lesson Overview:
This lesson is centered on the Bio-Rad pGLO Bacterial Transformation Kit. Students will examine
how a gene and associated trait from one organism can be isolated, transferred to another organism and
replicated. Students will also use the RAFT writing strategy to assess knowledge about the ethical
dilemma of cloning.
Lesson Core
 The Guiding Question:
What applications can be derived from bacterial transformation?
 Materials and Equipment Needed:
 Bio Rad pGLO transformation kit. ***This kit contains enough supplies for 2 classes of 32
students each. Additional equipment not included is listed below.
 Incubator (37 ° C)
 Hot water bath (42° C) Using DI water will prevent mineral deposits.
 2-4 U-V/ black lights (green fluorescent protein cannot be observed without this light)
 Ice and small Styrofoam cups
 Sharpie markers or wax pencils – 1 per group
 Masking tape
 Buckets or other containers with 10% bleach solution
 Safety precautions:
The E. coli used in this lab in non-pathogenic, but should be treated as such in the lab.
All participants should wear goggles and gloves. All lab supplies, except paper products,
should be placed in a 10% bleach solution and soaked overnight. Teacher can then place items
in a double plastic bag and place in the trash. Agar should NOT be disposed of down the sink drain as
it will solidify and block the drain.

Step 4
Organize student workstations
Immediately prior
10 min
Bacterial cultures need to be started 24 hours before the lab and should be no older than 36 hours. LB
and other plates can be made up to 1 week before the lab and stored in the refrigerator. Instead of
disposing of equipment after bleaching, many items can be washed in hot, soapy water and used for
other labs throughout the year. Autoclaving is another option.
 Background Information for Teachers: (from Bio Rad pGLO Transformation Kit)
In this lab, students will perform a procedure known as genetic transformation. Genetic
transformation occurs when a cell takes up and expresses a new piece of genetic material—DNA.
This new genetic information often provides the organism with a new trait, which is identifiable
after transformation. Genetic transformation literally means change caused by genes and involves
the insertion of one or more gene(s) into an organism in order to change the organism’s traits.
Genetic transformation is used in many areas of biotechnology. In agriculture, genes coding for
traits such as frost, pest, or drought resistance can be genetically transformed into plants. In
bioremediation, bacteria can be genetically transformed with genes enabling them to digest oil
spills. In medicine, diseases caused by defective genes are beginning to be treated by gene therapy;
that is, by genetically transforming a sick person’s cells with healthy copies of the defective gene
that causes their disease.
Genes can be cut out of human, animal, or plant DNA and placed inside bacteria. For example, a healthy
human gene for the hormone insulin can be put into bacteria. Under the right conditions, these bacteria can
make authentic human insulin. This insulin can then be used to treat patients with the genetic disease,
diabetes, because their insulin genes do not function normally.
With the pGLO transformation kit, students use a simple procedure to transform bacteria with a
gene that codes for Green Fluorescent Protein (GFP). The real-life source of this gene is the
bioluminescent jellyfish Aequorea victoria, and GFP causes the jellyfish to fluoresce and glow in
the dark. Following the transformation procedure, the bacteria express their newly acquired jellyfish
gene and produce the fluorescent protein, which causes them to glow a brilliant green color under
ultraviolet light.
In this activity, students will learn about the process of moving genes from one organism to
another with the aid of a plasmid. In addition to one large chromosome, bacteria naturally contain
one or more small circular pieces of DNA called plasmids. Plasmid DNA usually contains genes for
one or more traits that may be beneficial to bacterial survival. In nature, bacteria can transfer
plasmids back and forth, allowing them to share these beneficial genes. This natural mechanism
allows bacteria to adapt to new environments. The recent occurrence of bacterial resistance to
antibiotics is due to the transmission of plasmids.
 Engage:
This video clip from the 1931 movie version of is a great discussion starter on life and the idea of using
parts from other life forms to create a new life or new traits.
"Its Alive" Frankenstein Clip http://www.youtube.com/watch?v=8H3dFh6GA-A
This is a classic scene. Almost everybody has heard the famous line,” it’s alive." This scene sets up the
outlandish idea that you can take dead parts from a once living thing, put them together, shock it, and
create a new life. Nobody could actually think that it would be possible. However, in less than 100
years from the making of this movie science has unlock the secret of life, in the form of DNA, genes
and genetics.
 Building on prior knowledge:
After the clip, prompt the class with question about the reality of such an idea. Discuss the
difference between physical traits vs. genetic traits. How can a non-living thing bring about life? What
is the value of all the parts to make a whole organism, why not just half a man? There are a thousand
questions to ask and the students always have something to say or plenty of questions, which leads to
more discussion.
 Pre-teaching:
The units preceding the this unit would include mitosis / cell reproduction, a comprehensive unit on
DNA and protein synthesis. Much of the prior knowledge needed to link and understand concepts
would be taught in these preceding units. The PowerPoint from lesson plan 1 will also contain
background information important to this lesson
 Explore:
Bio-Rad pGLO Bacterial Transformation Lab (use kit)
The pGLO lab includes a detailed materials list, step by step and day by day instructions along with a
Teachers Guide with answers and a Student Manual with picture lab flow chart and questions. There is
little teacher prep, the students prep the lab the first day and spend the next 2 days on the experiment.
 Explain:
Students will complete Bio-Rad pGLO Bacterial Transformations Lab Data and Analysis with Review
Questions. Answers will be shared and discussed as a class. (Possible answers are included in BioRad pGlo Bacterial Transformation Lab manual. If time permits, students could instead create a lab
report with their findings.

RAFTS writing strategy- taken from:
http://udhscff.wikispaces.com/RAFT+Strategy
For this assignment I want you to think about what we have learned this semester
about the science behind stem cell/somatic cell research, cloning and the various
social and moral dilemmas that are associated with this controversial topic. Is this a
way that science could harm us, or help us? What are the repercussions? What does
cloning mean to mankind? You may take a position for or against, either way, just be
sure to defend your stance citing scientific facts and examples as well as note the
opposing side’s argument. Review the R.A.F.T. sheet attached, then, you must decide
who you would like to be when presenting your position. For example, you can be the stem cell
writing to the President or a clone writing to Congress. You may choose any writing style you would
like.

- Example
Dear My Beloved Body,
All I am is a tiny somatic cell, why does everybody make such a big deal about me? I am
asking you, my body, because it wasn’t that long ago that you tried to kill me. All I wanted was to go
pay a quick visit with a few of my neighbor somatic cells. I didn’t know there was already a party
going on over there, and, I must admit, it got extremely crowded. The next thing I can remember is we
were getting chemotherapy. Do you know that I lost some very dear friends and family during that
internal war? Not to mention I was sick for a long time. Now, here we are a few years later, and you
are trying to harvest me to make a new pancreas for yourself. You can’t seem to make up your mind!
First, you try to kill me, now you want to extract me and command me to do you a favor. What’s with
this therapeutic cloning, I thought they just cloned sheep?
My understanding of therapeutic cloning is they take me, one of your closest friends and
remove my nucleus. My nucleus is special to me, I really am not pleased to have it removed! Then, to
top it off, you want to stick my nucleus with an egg cell that has also had its nucleus removed! To
think, you want me to move in with someone I haven’t even met! To top that off, we both then need to
move to what I like to refer to as another planet – a uterus! This is where the union would produce an
offspring with my exact genetic makeup. I believe there are wonderful reasons to allow these types of
procedures. For example, there would no longer be a need for people having transplants to go on
immunosuppressant drugs. It would also allow patients to live a life without the potentially serious
side-effects of immunosuppresant drugs. More importantly, the ability to clonally derive organs would
alleviate the current shortage of transplants and would possibly reduce waiting times for translants to
become available. Conversley, if you were looking just to create another you, that would scare me.
Morally and ethically, there is only one you. You have been with me from birth and if this is what I
need to do to extend your life and make it better for you, then, for you my beloved body, I will do it.
Take care of your new organ, I wouldn’t want to have to do this again.
Love,
Your little somatic cell
