1. Apply the four steps commonly used
in genetic engineering experiments
to describe the cloning of a human
gene.
Human and vector DNA are cut and
then combined to produce recombinant
DNA. The recombinant DNA is inserted
into host cells. The host cells
reproduce, cloning the human gene.
The host cells are screened for the
gene.

4. Evaluate the role of probes in
identifying a specific gene.
Probes are pieces of single-stranded
DNA or RNA complementary to the
gene of interest. The DNA fragments on
the gel are made single stranded. The
probe will bind to any complementary
fragments. The genes are ideentified
because the probes are made with
radioactive or fluorescent-labeled tags.

on a DNA sample believes that her
smallest DNA fragment is the band
nearest the negative pole of the gel.
Do you agree with her conclusion?
Explain.
No. Disagree. DNA is negatively
charged and opposite charges attract.
The smallest fragments will move
fastest through the gel.

to the treatment of human illnesses
such as hemophilia.
Many genetically engineered proteins
are used to treat illnesses. For
example, factor VIII, a protein that
promotes blood clotting, is now made by
genetic engineering and sold as a drug
to hemophiliacs. Genetic engineers are
also attempting to replace defective
human genes with healthy ones.

Cloning with differentiated cells requires
that the cell be manipulated so that the
cell cycle is stopped.

concerns that genetically engineered
organisms might cause disease or have
harmful effects on the environment. By
limiting their survival outside the
laboratory, scientists are preventing the
organism from possibly harming people or
