Acids and bases are substances that are able to give and receive hydrogen ions respectively. This seemingly insignificant ability gives rise to a wide range of reactions and is essential for many biological processes. This pathway provides resources related to acids and bases, the types of reactions they undergo, and the pH scale which is used to measure the concentration of hydrogen ions in a solution.
This pathway will show you how to use your dashboard to add or create your own content, and how to remix it into customized learning pathways.
This interactive will present the mathematical consideration of exponentially
enriching a piece of DNA using PCR. Typically, a PCR protocol will repeat
approximately 30 cycles of denaturation, annealing, and elongation. 30 cycles of
PCR produce around 1 billion copies of the amplified region.
In this episode on Higher Ed’s Hidden Curriculum, Anthony Jack shares insights from his award-winning research on how inequality and poverty shape the life chances of college students. We also learn how Tony’s high school trajectory shaped his career, and discuss whether COVID-19 might inspire a new contract for higher ed’s commitment to disadvantaged students.
A new virtual interview series from LabXchange at Harvard University, the Xchange showcases the diverse roles, projects, and initiatives that make up the intersecting fields of science, education, and health. Hosted by LabXchange Faculty Director Robert Lue, our first season features a range of perspectives on the impact of COVID-19.
Este video describe algunas de las formas en que se puede aplicar la electroforesis en gel en el mundo real, desde la medicina forense hasta la clonación de genes.
To create HIV-resistant immune cells with the gene editing tool CRISPR-Cas9, a specific macrophage gene must be disrupted.
Questo video descrive alcuni dei modi in cui l'elettroforesi su gel può essere applicata nel mondo reale, dalla medicina legale alla clonazione genica.
This pathway introduces the building block of all matter, the atom, and some of the key experiments that helped scientists discover the subatomic particles that give atoms their unique properties.
In dieser Simulation werden das Wachstum von Bakterienzellen, die mit
einem rekombinanten Plasmid transformiert wurden, und die Expression
des Gens von Interesse mithilfe von selektiven Medien untersucht.
This pathway explores how physical features of a species can change over time in response to environmental factors influencing survival. Learn about well known case studies like Darwin's finches and peppered moths, and conduct your own investigations through simulations.
