DNA
Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.
Curated OER
DNA Cut and Paste Activity
Here is a cut and paste activity worksheet designed for older students. They fill in the blank with information about the composition of DNA, then create a DNA strand with its complimentary nucleotide chain.
Curated OER
The Structure of DNA
For this structure of DNA worksheet, students answer several short answer questions applying knowledge about the structure of DNA. Students also match the description to the correct terms.
Curated OER
Replication
In this replication worksheet, students color in the nucleotide outline and the enzymes plus the base pairs to show the replication of DNA.
Curated OER
The Double Helix
In this DNA learning exercise, students color in the parts of a DNA double-helix structure, which includes the base pairs and hydrogen bonds.
