Starting from a fictional "news" report about an apparent allergic reaction to a taco tainted by genetically modified corn, students consider some of the techniques and procedures used in modern molecular genetics and microbiology as well as some of the issues associated with genetically modified organisms (GMOs). Originally designed for role-play and PowerPoint assignments, suggestions for a shortened version are also provided. Suitable for a general microbiology course, the case could also be used in an introductory molecular biology course with appropriate modifications. Various levels of coverage of the topic of recombinant DNA are possible.

Molecular biological techniques are used to study naturally occurring genetic variation, and have greatly facilitated the understanding of problems in many areas of biology. In this lab, we examine two populations of terrestrial isopods in the Family Armadillidiidae using Random Amplification of Polymorphic DNA (RAPD Analysis). RAPDs are robust and generally species-independent. Using this technique, we are able to detect and analyze genetic variation within and between two different populations of isopods. This lab exercise could easily be modified for use in an introductory course for majors or non-majors and would be suitable for any organism with low vagility.

This chapter describes a multi-week project taught in an upper level cell and molecular biology laboratory. Isolation of sufficient quantities of rare proteins from biological tissues can be difficult. These native proteins are often required for raising antibodies, and for studying enzymatic or regulatory function. Expression vectors are used to obtain large quantities of proteins. The cDNA encoding a protein is cloned into an expression vector. The fusion protein is over-expressed in E. coli, and large quantities of the recombinant protein are obtained by affinity chromatography. SDS-polyacrylamide gel electrophoresis is used to determine the size of the proteins isolated.

This lesson for students in grades 9-12 introduces DNA, genes, chromosomes, the chemicals that make up DNA. After the basic information, students will do an experiment in which they will separate out DNA from peas. Knowing that DNA can be separated will give them a base of understanding for future lessons in biology, evolution, biotechnology, and health technology.

“A Family in Need” was designed as an in-class problem-based learning activity for students to learn about several innovative medical applications of molecular biology. Students assume the role of a second-year medical student assigned to work with a pediatric oncologist who has just biopsied a tumor-like growth in the adrenal gland of her 17-year-old patient, Lee F. After taking Lee’s family history and performing a pedigree analysis, students review clinical and genetic characteristics of several syndromes associated with adrenal cancer. Students then explore various diagnostic and biomedical research techniques such as PCR, DNA sequencing, and pre-implantation genetic diagnosis. The case concludes with a consideration of how to treat Lee’s condition with the help of gene cloning and the potential of gene therapy. Although originally written for an upper-level college genetics course, the case could also be adapted for an introductory molecular/cellular biology course, a non-majors biology course, or a professional school medical genetics course.

This course introduces the basic driving forces for electric current, fluid flow, and mass transport, plus their application to a variety of biological systems. Basic mathematical and engineering tools will be introduced, in the context of biology and physiology. Various electrokinetic phenomena are also considered as an example of coupled nature of chemical-electro-mechanical driving forces. Applications include transport in biological tissues and across membranes, manipulation of cells and biomolecules, and microfluidics.

Samples of soil were recovered from an Indiana murder victim's car and shoes. This experiment isolates DNA from plants grown from seeds that were found on the shoes. Two different ecotypes of a weed grow in different areas of Indiana. This difference can be detected using the polymerase chain reaction (PCR). DNA is extracted from the seedlings using the REDExtract-N-Amp Plant PCR Kit. Specific regions of the isolated DNA are then amplified by PCR. The PCR products are analyzed by gel electrophoresis and the results used to determine which suspect was in the same area as the victim. With data from previous exercises the students can determine who committed the murder. An alternate CTAB DNA isolation procedure is also included.

Since the discovery of the structure of the DNA double helix in 1953 by Watson and Crick, the information on detailed molecular structures of DNA and RNA, namely, the foundation of genetic material, has expanded rapidly. This discovery is the beginning of the "Big Bang" of molecular biology and biotechnology. In this seminar, students discuss, from a historical perspective and current developments, the importance of pursuing the detailed structural basis of genetic materials.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes. Learners use simple materials to assemble a comb (electrophoresis chamber) to hold the samples, make a 0.2% sodium bicarbonate buffer and 1% gel solution, connect a high voltage power supply, and prepare 5 different samples. Then learners test their model and observe each sample.

This exercise allows students to investigate the genetic control of a biosynthetic pathway: the production of the red pigment prodigiosin by the bacterium Serratia marcescens. The students perform feeding trials with mutant strains to examine the genetic control of this biosynthetic pathway. Auxotrophic strains of the bacteria which are blocked at different places in the pathway exhibit different colors, the wild-type is a deep red color. Pairwise feeding trials enable the students to determine which strains are blocked at which point in the pathway. Students will then use an explanatory system to determine the pathway's shape and learn about its genetic control.

In this intimate debate case, students consider whether to support the development and use of Golden Rice as a means to alleviate vitamin A deficiency in the developing world. Since many of the arguments typically raised against genetically modified organisms (GMOs) do not apply to this particular GM crop, students are forced to analyze the facts rather than rely on what they have heard in the media. Developed for an introductory molecular biology undergraduate course, the case could also be used at more senior levels.
