Genetic Engineering Vs. Traditional Breeding Timeline This animation compares the timeline for genetic engineering versus traditional plant breeding. It also compares the regulatory processes of each.
Genetic Mapping An overview of how genes affect an organism's traits, and how those genes are passed from one generation to the next. Also explains how scientists map locations of genes on chromosomes.
Instructions to Create a PBTN Account
Lateral Flow Strip Test This animation illustrates the concepts of protein detection using the lateral flow strip method. This method is simliar to ELISA and is utilized in detecting GMOs, among other applications.
Making a Gene Library This animation shows how to make a colony of new DNA in order to locate a specific gene of interest. This is the third of four animations detailing the gene cloning process. To begin at the beginning, choose Making a Recombinant Plasmid. (The animation prior to this one is Bacteria Transformation. The animation just after this one is Screening a DNA Library.)
Making a Recombinant Plasmid This animation shows how a plasmid responsible for encoding a gene can be cut. The plasmid can be altered with the addition of linear DNA to form a recombinant plasmid to encode a new gene of interest.
This is the first of four animations detailing the gene cloning process. The other three animations are Bacteria Transformation, Making a Library, and Screening a DNA Library.
Marker Assisted Selection An animation showing how plant breeding has changed over time, including the use of molecular markers.
Overview of Crop Genetic Engineering A general look at the process of crop genetic engineering.
This is the first of a series of seven animations that detail the process of crop genetic engineering. The six lessons after this are DNA and DNA Extraction, Gene Cloning, Gene Regions, Gene Modification, Gene Gun, and Backcross Breeding.
Overview of plant breeding strategies
Plant Breeding Activity This interactive activity goes through the basic process used in a traditional breeding program. Crossing, genetic variation, selection and elements of DNA technology are discussed within this activity. The material is aimed towards high school or introductory life science undergraduate students.
Polymerase Chain Reaction (PCR) This animation depicts the process of PCR. Each component involved in the process is outlined and described in this animation.
Protein Synthesis: Transcription/Translation Overview This animation shows the transcription process of RNA within the plant cell. Single stranded RNA moves out of the cell where it is translated into proteins. This is the first in a series of three animations on protein synthesis. The other two animations are Transcription and Translation.
Screening a DNA Library This animation shows how scientists find the gene of interest by screening thousands of bacteria. Scientists can screen the protein or the DNA. This is the fourth of four animations detailing the gene cloning process. To begin at the beginning, go to Making a Recombinant Plasmid. To view the animation before this one, go to Making a Gene Library.
Taqman The Taqman probe detection system used in real time PCR (also known as quantitative PCR) is illustrated in this animation. One application of this method is use in GMO detection.
Transcription A detailed depiction of transcription, the first stage of protein synthesis. This is the second in a series of three animations on protein synthesis. To begin at the beginning, go to Protein Synthesis - A general overview.
Transgene Design This is an interactive animation that asks the viewer to design a gene by selecting the promoter and coding region that will produce a plant with the desired traits.
Translation A detailed depiction of translation, the second stage of protein synthesis. This is the third in a series of three animations on protein synthesis. To begin at the beginning, go to Protein Synthesis - A general overview.
