Examine the physical properties of onion DNA.

  • Aligned to NGSS standards(HS: PS1, PS2, LS1, LS3)
Easily extract the DNA from a large onion to view its macromolecular structure. A macromolecular solution, which has similar characteristics to DNA, is also included for comparison of long, linear-chain molecules. The class-size activity comes with everything you need to perform the lab but an onion. The demonstration size comes with an onion lysate already prepared. The lab activity may be completed in 15 minutes or less. The class size comes with enough materials for six setups, a teacher’s guide, and student copymaster.

Activity 1: 30 minutes.

Activity 2: 45 minutes.

The kit is also available for purchase with a link to a NewPath digital lesson, which includes a variety of resources on the topic, including background information, illustrations and self-assessments.
