Dynamic 3D DNA Model (3′ FT Long)

Description

Our flexible dynamic DNA model is a 38-inch double helix that students hold, twist and unzip. As a result, a flat textbook diagram becomes something the whole class can see and touch.

Why teachers choose this flexible dynamic DNA model

Each of the 21 rungs has its own color, so students match base pairs at a glance. In addition, the colors work as a memory aid, with one color for each base. Because the ladder bends, you can show the twist of the helix. Then you can lay it flat to count pairs.

Epigenetics made visible

The model also includes epigenetic methyl-switches. For example, students flip a switch to see how a cell turns a gene on or off without changing the DNA sequence. So a hard topic becomes clear in a single lesson.

Teach DNA replication hands-on

First, students use the “unzipping” action to pull the two strands apart, just like a cell does before it copies its DNA. Next, they rebuild each half. Finally, they discover why every new molecule keeps one old strand. After all, learners remember what they build with their own hands.

For background reading, the National Human Genome Research Institute offers a clear DNA fact sheet. It also pairs well with the flexible dynamic DNA model.

A free course is included

Every model comes with a complementary course, so you skip the lesson planning. In fact, you can explore the curriculum before you buy. Want to go further? Then add the umber RNA tubes to show how DNA becomes RNA. You can also add a Friends Kit to model protein synthesis.

Who uses the flexible dynamic DNA model

Biology teachers, homeschool families, tutors and students use it every day. For instance, it works for a quick demo at the front of the room. Likewise, it works for small groups at a table. Click Add to Cart and finish checkout. After that, we email your order confirmation right away.
