Product Description
This model is a simple way to study the structure of DNA. Not only will you see how the base pairs combine, but you can also twist the model to show the double helix. Once you’ve put it together, you can pull it into two halves and construct two identical strands of DNA demonstrating how DNA replicates. 

Use this to learn and reinforce answers to questions such as:
❑ Which bases combine with each other?
❑ How are base pairs organized in a DNA molecule?
❑ How does DNA replicate?

Once students walk through the sequence of events, they can capture their observations using the included Lab Notes or probing questions included in the instructions. 

Answer Keys and Teacher Notes address most questions and issues that might arise in this study—you shouldn’t have to do any outside research unless you want to.

Concepts Addressed
♦ One molecule or strand of DNA comprises a single chromosome.
♦ DNA molecules split lengthwise before duplicating.
♦ In DNA, only specific bases can combine with each other.

Materials Needed   
Nonconsummables: pony beads in four colors, pipe cleaners, plastic straws

Prep TimeIt will take time to make the beaded pipe cleaners, but once made they should last for years.

Teaching Time   About 40 mins.

Student Sheets   Scaffolded writing prompts & lab reporting
