Enzyme and Southern Blotting

Young scholars use the prelab as an introduction to the importance of DNA fingerprinting- a form of identification that us being accepted by both scientific and leagl experts. They prepare a gel for electrophoresis. DNA fragments, which...

Student demonstrate knowledge of recombinant DNA techniques (restriction enzyme digest, gel electrophoresis, and staining gel). They demonstrate skills needed to complete a gel electrophoresis and interpret a stained gel. Pupils solve...

Ever wonder how scientists determine how animals are related, or who is guilty of a crime? Discover gel electrophoresis in an easy-to-understand video from a fun biology playlist. Topics include how restriction enzymes create segments of...

Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

The Northern blot and the Southern blot are two methods used to analyze DNA and RNA. Each technique is described, its purpose, and the methodology. A table comparing features of each is provided.

The chances of a DNA mismatch occurring in DNA fingerprinting is one in a billion. Here learners see how using the differences in people's DNA, specifically Short Tandem Repeats (STRs), cutting them out using restriction enzymes, and...

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

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....

Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...

Get your class to take a closer look at DNA. Pupils conduct research to determine the methods used by scientists to analyze the molecular structure of DNA. The class members investigate different types of molecular imaging along with gel...
