Explore the bacteria at Yellowstone to introduce molecular biology. Scholars learn about the process of genetic engineering and how it has progressed over time, including the identification of the breast cancer genes and the main...

In this molecular biology worksheet, students complete 50 multiple choice questions on DNA and RNA replication, translation and transcription.

Future geneticists use base pairing rules to build DNA and RNA polypeptide strands, and then explain both transcription and translation. Although the chains themselves are a little blurry, there is plenty of room in them for learners to...

Many define biology as the study of life but can't agree on a definition of life. Trying to explain all of the domains and subdomains of biology seems a bit easier than defining life. See a full map of the topics covered by the general...

What does it take to win a Nobel Prize? Scholars learn about molecular machines, the theme of the 2016 Nobel Prize in Chemistry. It explains how the three winners have each contributed to this field of science.

Scholars compare and contrast the molecular changes for short-term and long term-memory with the help of animated videos. Viewers see the chemical process that changes the brain and stores memories thanks to dopamine.

Focus on macro-molecules including nucleic acids, proteins, lipids, and carbohydrates. A video explains which are monomers, which form polymers, and the process of changing from one to the other. It also covers the characteristics of...

What if buildings could grow, adapt, and repair themselves like a living organism? Using the process of self-assembly, this crazy idea may one day become a reality. The video looks at how unordered parts interact with one another and...

Neurons don't touch each other, but they still communicate. Observe the process of both electrical and chemical signals used by neurons to share information. Hear exactly what triggers each step of the reaction as you view an animation...

The heartbreaking story of Alfred Wallace's loss of collected evidence opens this documentary about the development of the theory of evolution. You will find supportive resources to use with the movie in your biology class.

An upper-level biology activity, the comprehensive worksheet found here accompanies a PowerPoint and the video The Making of the Fittest: The Birth and Death of Genes, both of which are linked to through the website. Depending on the...

Biodiversity begins at the molecular level. When biology pupils complete this learning exercise, they will explore a variety of organic compounds that are necessary for life. Six short-answer questions and a chart of the functional...

Antibiotics kill bacterial growth, but widespread use results in antibiotic resistance. Researchers wonder if quorum sensing might allow us to treat bacteria without the resistance. View an animation of quorum sensing as it regulates...

Advanced placement biology aces list systems that have evolved over time, adaptations, and structure-function relationships. The resource requires plenty of writing to answer these questions, so allow a few days for them to complete the...
