Lesson notes

Learning Objectives

Indicator: 3.1.2.LI.3 - Describe how genetic recombinant technology is applied in biotechnology to produce GMOs.

By the end of the lesson, learners can:

Define genetic recombinant technology (recombinant DNA technology) and genetically modified organisms (GMOs) in their own words.
Describe the key steps involved in producing a genetically modified organism, from gene isolation to the expression of the new trait.
Construct a labelled flow chart showing the sequence of events in recombinant DNA technology.
Identify examples of genetically modified crops and animals produced in Africa using recombinant DNA technology.
Discuss the socio-cultural, economic and emotional concerns that communities in Ghana may have about GMOs and genetically modified crops, using evidence from research.

Exemplars (from the NaCCA curriculum)

Group-Based Learning:
- In mixed ability, all-inclusive groups, listen to a presentation by a resource person or your teacher on genetic recombinant technology also known as Recombinant DNA technology (rDNA) and note down your observations and discuss them: Learners develop teamwork and involvement attitude.
- Design a flow chart on the key processes involved in this technology. Learners contribute to assigned tasks, thereby building self-confidence and respect.
Group Project-Based Learning: in mixed-ability, all-inclusive groups, learners read/research from textbooks, libraries, journals and newspapers to acquire further information on genetically modified crops and animals in Africa produced using recombinant DNA technology. Learners gain broader understanding on the socio-cultural and emotional concerns on genetically modified organisms and crops (GMOs and GMCs) and educate families and the masses on these beliefs. Learners share information and acknowledge the efforts of peers.
