Unlocking the Secrets of DNA: The Blueprint of Life

Learning objective

Learning Objective

At the end of the lesson you will understand DNA's structure, function in cells, and how it influences traits.

What do you already know about DNA and its role in cells?

What is DNA?

DNA stands for Deoxyribonucleic Acid. It's a molecule that carries genetic instructions for all living things.

DNA Structure

DNA has a double helix shape, like a twisted ladder. Its sides are sugar and phosphate, with base pairs as steps.

Interactive: Build DNA

Activity: Use coloured paper strips to model DNA's structure. Match base pairs: A with T, and C with G.

DNA in Cells

DNA is found in the cell's nucleus. It controls cell activities by giving instructions to make proteins.

Genes and Traits

Genes are sections of DNA. They determine traits like eye colour. Each person has a unique DNA sequence.

Interactive: DNA and Traits

Activity: Identify traits by comparing earlobe attachment and thumb flexibility with classmates.

Summary and Reflection

DNA is the blueprint of life, affecting traits and cellular functions. Reflect on how DNA connects to your life.
