CHAPTER 9: The Biotechnology
Revolution
- The Zoological Society of San Diego: International Conservation
- The conservationists at the San Diego Zoo deal with breeding
problems every day. Take a look at breeding challenges at the
center, from fussy cheetahs to captive condors.
- Preserving Florida's Biodiversity
- How is Florida coping with loss of species and genetic diversity
within a species? This chapter from the Florida Internet Center
for Understanding Sustainability describes the problems facing
the Florida panther and other species in the Everglade State.
- National Center for Genetic Resources Preservation
- This research station of the U.S. Department of Agriculture
is a kind of genetic warehouse, preserving important seeds and animal material to ensure genetic diversity. Visit their Web site to learn about
what they do and why.

- Hello, Dolly
- Online science magazine The
Why Files investigates the science of cloning--how Dolly
was created, who else paved the way for this ewe with three mothers,
and the potential applications of cloning. And hey, is Dolly
an exact replica of her genetic predecessor Belinda? Read this
fascinating and fun article and form your own opinion.
- Recombinant DNA
- This chapter from the MIT Hypertextbook covers cloning
into plasmids, molecular cloning techniques, and the polymerase
chain reaction.
- Access Excellence
- This is a top-notch educational site. One of the best sections is About BioTech.

9.3 APPLICATIONS OF GENETIC ENGINEERING
- Your DNA I.D. Card
- How do you make a DNA fingerprint? This page comes from an
article on forensic science by online science magazine The
Why Files. It briefly describes the procedure used, identifies
related problems, and gives further references for a more detailed
explanation.
- Mystery of the Stolen Artifacts
- Help prosecute an artifact plunderer by looking at the protein
fingerprint of three types of daisies. This crime lab activity
was created by the Utah Museum of Natural History.
- Blackett Family DNA Activity
- Take a look at the family of DNA analyst Bob Blackett. You
won't see pictures, but you will interpret DNA autoradiograms
and evaluate DNA profiles to determine familial relationships,
while also learning about RFLP markers.

9.4 SAFETY AND ETHICS IN BIOTECHNOLOGY
- Mice & Men: Making the Most of Our Similarities
- Learn about how the Oak Ridge National Laboratory has created
mice to model sickle-cell anemia, cleft palate, diabetes, and
obesity. This article is sprinkled with pictures and quotes from
the scientists who engineered these rodents.
