DNA Structure

Updated on 02/05/2016

Activity Overview

In this lesson, students use a variety of simulations to interact with the structure of DNA in order to explore the building blocks and double helical structure of DNA.

Objectives

  • Students will learn about the structure of DNA, including base pairing.
  • Students will be able to predict paired sequences of DNA.
  • Students will understand how the structure of DNA affects its function.

Vocabulary

  • Nucleotide
  • Phosphate backbone
  • Adenine
  • Cytosine
  • Ribose
  • Base pair
  • Double helix
  • Thymine
  • Guanine
  • Deoxyribonucleic acid

About the Lesson

Using a variety of simulations, students will interact with the structure of DNA to explore the building blocks and double helical structure of DNA. Assessments are embedded in the activity to engage discussion and gauge learning.

As a result, students will:

  • Learn to recognize the general structure of DNA and its nucleotides the nitrogen base, deoxyribose sugar and the phosphate.
  • Learn to apply Chargaff's rules for base pairing, including predicting the sequence of paired DNA strands.
