Chapter 9: Frontiers of Biotechnology

Restriction Enzymes

Animated tutorial illustrating how restriction enzymes are used to cut DNA

http://www.dnalc.org/resources/animations/restriction.html

http://www.dnalc.org/resources/animations/restriction.html

(Main Idea: Restriction enzymes cut DNA.)

 

 

Gel Electrophoresis

Virtual lab in which you use restriction enzymes to cut DNA into fragments, then perform gel electrophoresis to make a restriction map

http://www.scq.ubc.ca/dna-restriction-digest-and-gel-electrophoresis-a-virtual-lab/

(Main Idea: Restriction maps show the lengths of DNA fragments.)

 

 

PCR

Virtual lab in which you use PCR to amplify a sample of DNA

http://learn.genetics.utah.edu/content/labs/pcr/

(Main Ideas: PCR uses polymerases to copy DNA segments. PCR is a three-step process.)

 

 

DNA Fingerprinting

Simulation in which you use DNA fingerprinting to identify a culprit

http://www.teachersdomain.org/asset/tdc02_int_creatednafp2/

(Main Ideas: A DNA fingerprint is a type of restriction map. DNA fingerprinting is used for identification.)

 

 

Cloning

Multimedia describing what cloning is, including animations comparing natural reproduction to cloning; information on cloning myths and the risks and benefits of cloning

http://learn.genetics.utah.edu/content/tech/cloning

(Main Idea: Entire organisms can be cloned.)

 

 

Recombinant DNA

Video describing how a gene from one organism can be inserted into another organisms using recombinant DNA

http://www.learner.org/courses/biology/archive/animations/hires/a_gmo1_h.html

(Main Idea: New genes can be added to an organism’s DNA.)

 

 

Genetic Engineering of Insulin

Animation illustrating how bacteria are genetically engineered to produce human insulin

http://www.abpischools.org.uk/res/coResourceImport/modules/hormones/en-flash/geneticeng.cfm

(Main Idea: New genes can be added to an organism’s DNA.)

 

 

Genetic Modification of Food

Simulation in which you go through the steps to create a transgenic insect-resistant tomato plant

http://www.pbs.org/wgbh/harvest/engineer/transgen.html

(Main Idea: Genetic engineering produces organisms with new traits.)

 

 

The Human Genome Project

Click on “The human genome” for an interactive tutorial describing how the human genome was sequenced.

http://www.yourgenome.org/downloads/animations.shtml

http://www.yourgenome.org/downloads/animations.shtml

(Main Idea: Genomics involves the study of genes, gene functions, and entire genomes.)

 

 

DNA Microarrays

Virtual genomics lab in which you use a DNA microarray to compare gene expression in healthy cells and cancer cells

http://learn.genetics.utah.edu/content/labs/microarray/

(Main Idea: Technology allows the study and comparison of both genes and proteins.)

 

 

Genetic Screening

Video explaining how genetic screening may help people determine their predisposition for genetic diseases

http://www.teachersdomain.org/asset/biot09_vid_prsnldna/

(Main Idea: Genetic screening can detect genetic disorders.)
