The discovery of restriction enzymes and their applications in DNA analysis has proven to be essential for biologists and chemists. This lesson focuses on restriction enzymes and their applications to DNA analysis and DNA fingerprinting....

Learn about restriction digestion, where the result has sticky ends and blunt ends. Also find out about ligation reactions.

This site is a retired biology professor's explanation of restriction enzymes. Good visual showing examples of how enzymes cut DNA to produce blunt or sticky ends.

Searchable database of restriction enzyme information. Must have more than basic knowledge of restriction enzymes.

Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint")...

Animated slide show demonstrates the genetic engineering process of DNA restriction.

Tutorial explains the processes of restriction digestion and gel electrophoresis and provides an interactive exercise to further your understanding.

[Free Registration/Login Required] Following basic lab techniques of modern molecular biology, analyze the gel electrophoresis results of a restriction enzyme digest of DNA by using a HindIII-generated standard curve. Then solve two...

Explore practical uses of genetic engineering techniques to generate a plant that produces a hepatitis B protein for potential vaccine use. Examine the use of restriction enzymes for cloning and plasmid mapping.

Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change...

A great step by step site for how DNA is prepared and plated in the process of electrophoresis.

Worldwide, millions of people are infected with the hepatitis B virus (HBV) and the world is in need of a resourceful and inexpensive vaccine. In this case study you will learn how to generate a plant that produces a hepatits B protein...
