Biology: Recombinant DNA
by Texas Instruments - Simulation Lesson


  • Students will explore how scientists are able to isolate and study single genes.
  • Students will be introduced to recombinant DNA and the molecular biology of cloning.
  • Students will become familiar with the process of bacterial transformation, as well as with important molecular biology tools, including restriction enzymes, plasmids and ligase.

About the Lesson

Using simulations, students complete the steps required to clone a single gene and express it in a model organism. Assessments are embedded in the activity to engage discussion and gauge learning.
As a result, students will:

  • Learn about the process of molecular genetics, including restriction enzymes, ligation, DNA transformation and the use of model organisms.
  • Learn how scientists isolate a gene, recombine DNA and express that DNA in bacteria.
