Subject: Biology
Lesson Topic: define the term recombinant DNA
Learning Objective/s:
  • Describe the definition of recombinant DNA and how it differs from natural DNA.
  • Identify the key components (gene of interest, vector) and the sequential steps used to create recombinant DNA.
  • Explain the purpose and major applications of recombinant DNA technology in biotechnology.
Materials Needed:
  • Projector or interactive whiteboard
  • PowerPoint slides with diagrams of the recombinant DNA process
  • Handout summarising the six steps and the natural vs. recombinant DNA comparison table
  • Printed plasmid/vector diagram for labeling activity
  • Short video clip showing restriction digestion and ligation (animation)
  • Worksheets for guided practice and exit‑ticket
 Introduction:
Begin with a brief video of a scientist inserting a gene into a bacterial plasmid to spark curiosity about engineered traits. Review students’ prior knowledge of DNA structure and the role of vectors. State that by the end of the lesson they will be able to define recombinant DNA, outline its creation steps, and discuss its biotechnological uses.
Lesson Structure:
  1. Do‑now (5') – Quick quiz on DNA basics and vector concepts.
  2. Mini‑lecture (10') – Definition of recombinant DNA, comparison with natural DNA, using slides and the comparison table.
  3. Guided walkthrough (15') – Step‑by‑step explanation of the six recombinant DNA procedures (isolation, restriction digestion, ligation, transformation, selection, expression) with the schematic diagram.
  4. Group activity (10') – Students label a blank diagram of the process on handouts and discuss the purpose of each step.
  5. Check for understanding (5') – Exit‑ticket: write a single sentence defining recombinant DNA.
  6. Summary & homework preview (5') – Recap key points and assign a short research task on a real‑world product created using recombinant DNA.
Conclusion:
Recap that recombinant DNA is artificially assembled DNA combining genetic material from different organisms, enabling new traits and protein production. Invite a few students to share their exit‑ticket definitions for immediate feedback. Assign homework: research one real‑world product derived from recombinant DNA and prepare a one‑minute summary for the next class.
