Biology 336 is offered once a year. To enroll in Biology 336, students must have previously passed Biology 311 (Genetics). This course satisfies the Molecular and Cellular component of the Biology major.

Biology 336 consists of both lab and lecture. The lecture portion of the course will cover a wide range of topics. Some of the topics to be covered include the study of DNA, genetic imprinting, synthesis of recombinant DNA molecules,the synthesis of gene libraries, methods of detecting genes in libraries, DNA sequencing, Nothern/Southern/Western blots, site-directed mutagenesis, eucaryotic RNA processing, the genetic regulation of iron metabolism, transcription factors, DNase footprinting, mobility shift assays, gene organization in eucaryotes, and making transgenic animals.

The lab portion of the course is fairly extensive and serves to provide a good foundation for acquiring skills in the science of molecular biology. Students will construct a restriction site map of an unknown plasmid. This will enable them to become very familiar with three basic lab skills: 1. Plasmid DNA isolation from bacteria; 2. Restriction enzyme digests; and 3. Agarose gel electrophoresis. Some of this work may be conducted outside class time.

In addition, students will also gain hands-on experience with the following techniques during lab:

  1. PCR
  2. Transformation of yeast
  3. Replica-plating
  4. Making competent bacteria and bacterial transformations
  5. Protein isolation from yeast
  6. SDS polyacrylamide gel electrophoresis
  7. Western blotting
  8. Yeast plasmid isolation
  9. Synthesis of recombinant DNA molecule
  10. Southern blotting
  11. Enzyme assay
  12. Determination of DNA and protein concentrations
