This interactive image allows the user to control the environmental temperature
and observe its impact on the strength of the hydrogen bonds between
complementary strands in a DNA molecule.
This interactive image allows the user to control the environmental temperature and observe its impact on the folding of albumin proteins in egg whites.
In this interactive image, you will control the pH of the environment to see how it impacts the biological activity of a restriction enzyme.
Different mutations have different effects on the gene product, the protein. This scrollable explores the various types of genetic mutations CRISPR-Cas9 editing can induce in target DNA and their effects on the protein.
Students test the question, "Do eggs balance on the equinox?" Students develop their own procedure, analyze their data and come up with their own conclusions.
Met deze simulatie kunnen gebruikers verkennen hoe een interessant
eiwit, rood fluorescerend eiwit, gezuiverd kan worden uit cellysaat met
behulp van hydrofobe kolomchromatografie.
Esta simulación introduce la electroforesis en gel, una técnica utilizada
para separar moléculas biológicas. En esta simulación, la electroforesis en
gel se utiliza para separar tintes y visualizarlos en un gel de agarosa.
Essa simulação introduz a eletroforese em gel, uma técnica usada para
separar moléculas biológicas. Nessa simulação, a eletroforese em gel é
usada para separar corantes e visualizá-los em um gel de agarose.
Questa simulazione presenta l’elettroforesi su gel, una tecnica utilizzata
per separare le molecole biologiche. In questa simulazione, l’elettroforesi
su gel viene utilizzata per separare i coloranti e visualizzarli in un gel di
agarosio.

This classroom activity introduces students to energy flow through organisms, producers & photosynthesis, and consumers & respiration.
This pathways explores how cells harvest energy using cellular respiration in eukaryotic cells and photosynthesis in plant cells.
This biomimetic engineering challenge introduces students to the fields of nanotechnology and biomimicry. Students explore how to modify surfaces such as wood or cotton fabric at the nanoscale. They create specialized materials with features such as waterproofing and stain resistance. The challenge starts with student teams identifying an intended user and developing scenarios for using their developed material. Students then design and create their specialized material using everyday materials. Each students test each design under specific testing constraints to determine the hydrophobicity of the material. After testing, teams iterate ways to improve their self-cleaning superhydrophobic modification technique for their design. After iterating and testing their designs, students present their final product and results to the class.

This pathway provides an introduction to enzymes, their properties, and how they affect biological reactions. For a deeper look at this topic, we recommend the pathway Metabolism from the OpenStax textbook Biology for AP® Courses.
This pathway introduces a specific class of proteins called enzymes that are integral to catalyzing many biological reactions.
