Educator Guide: Woolly Mammoth DNA and A New Element

Take note — there could soon be a new element on the block. By smashing atoms together, scientists have been expanding our periodic table of elements beyond what occurs in nature. Learn how scientists create them while answering questions and discussing how such innovations may help us in the future.

Scientists have been able to study genetic activity in an ancient woolly mammoth’s DNA, thanks to a new method. Learn about the research study and the preservation of the DNA while thinking through the implications of having certain genes turned on or off.

Scientists studied ancient woolly mammoth DNA that had been freeze-dried in place, preserving it and retaining its shape. The researchers adapted a technique for studying the structures of chromosomes within a nucleus to determine which genes were turned on and off in the mammoth genome. In this activity, students will review what happens when genes are turned on by completing exercises that illustrate hypothetical DNA base pairing and simplified examples of transcription and translation.
