Microlearning Lesson Plan: Mitochondrial DNA
Category:
Biology
Lesson 1: Introduction & Fundamentals
*Objective:* Understand what Mitochondrial DNA (mtDNA) is and its role in
cellular function.
– *Definition:* Mitochondrial DNA (mtDNA) is the small circular chromosome
found inside mitochondria, often referred to as the powerhouse of the cell.
It plays an essential role in energy production and is inherited maternally.
– *Key Concepts:*
– The structure and location of mtDNA.
– Mitochondria’s function in energy production.
– Maternal inheritance pattern.
*Resources:*
– Article: [Mitochondrial DNA – Wikipedia](
en.wikipedia.org/wiki/Mitochondrial_DNA)
– Video: [What is Mitochondrial DNA? Three Fun Facts About mtDNA](
https://www.youtube.com/watch?v=S-URLagiLTM)
*Key Takeaways:*
– Understand the basic structure and function of mtDNA.
– Recognize the unique inheritance pattern of mtDNA.
*Reflection Exercise:* Write a short paragraph summarizing why mtDNA is
exclusively maternally inherited.
Lesson 2: Practical Application & Techniques
*Objective:* Explore how mtDNA is applied in real-world scenarios, such as
disease research and forensic science.
– *Practical Applications:*
– Role of mtDNA in diagnosing mitochondrial diseases.
– Use of mtDNA in tracing genetic lineage and ancestry.
– Application in forensic science for identifying individuals.
*Resources:*
– Article: [Mitochondrial Diseases: Causes, Symptoms & Treatment](

*Key Takeaways:*
– Learn how mtDNA is used in medical diagnostics and treatment.
– Understand forensic applications of mtDNA in solving cases.
*Activity:* Identify an example of a disease linked to mtDNA mutations and
describe its impact on human health.
Lesson 3: Advanced Insights & Mastery
*Objective:* Gain advanced understanding of recent developments in mtDNA
research and future directions.
– *Advanced Insights:*
– Current advances in genetic engineering targeting mtDNA.
– Debate on paternal inheritance of mtDNA.
– The impact of mtDNA research on understanding human evolution.

*Key Takeaways:*
– Discover new genetic engineering techniques and their implications.
– Consider ethical and evolutionary questions emerging from mtDNA studies.
*Reflection:* Debate (pro/con) the ethical implications of genetic
modifications to mtDNA.
