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.

Acerca de este video: Esta animación describe la estructura de una célula procariota y el modo en que se altera para permitir que se produzca la fisión binaria.

Esta animação descreve a estrutura de uma célula procariótica e como ela é alterada para permitir que a fissão binária ocorra.

This pathway explores the concepts of natural selection and evolution of populations. Stories from scientists sharing their perspective on this topic and their research are embedded throughout the pathway.

The application of Cas9-fusion proteins creates a greater cellular toolbox beyond gene disruption.

This simulation provides an arena where experimental design can be
practiced. To answer a specific research question, learners generate a
sequence of laboratory techniques to reach the desired goal themselves.

The experimental design simulations developed by LabXchange allow learners to construct a sequence of laboratory techniques to answer a specific research question.

This pathway provides an introduction to LabXchange, how it can support learners and educators, and the types of content you can find on LabXchange.

This pathway explores innovations in biotechnology that have revolutionized aspects of modern life like agriculture, forensics and medicine.

In this video, learners will explore the power of fluorescence microscopy to study cell biology.

Taking advantage of fluorescence has greatly increased the arsenal of laboratory techniques to study biological processes.

This pathway explores the concept of forces. The basic techniques of vector algebra are discussed, which allows for an introduction to Newton's Three Laws of Motion, which describe how objects react when forces are applied to them. The pathway concludes with a series of questions for students to test their understanding.

Questa simulazione offre l’opportunità di fare pratica eseguendo una reazione di ligazione in un laboratorio virtuale. Questo processo utilizza l’enzima DNA ligasi per collegare due frammenti di DNA usando estremità complementari smussate o estremità coesive generate dalla digestione di un enzima di restrizione.

What do a lab and an orchestra have in common? What is the link between air pollution and COVID-19? In this episode of the Xchange, Rob Lue and pioneering data scientist Francesca Dominici discuss these topics and more. Co-director of the Harvard Data Science Initiative and Clarence James Gamble Professor of Biostatistics, Population and Data Science at the Harvard T.H. Chan School of Public Health, this is Francesca Dominici in the Xchange. 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 interactivo desplegable explora las diferentes funciones que las proteínas pueden desempeñar en la célula. Las categorías de proteínas cubiertas incluyen las proteínas transmembranales, las proteínas que conforman las máquinas moleculares como los cilios y los ribosomas y las enzimas. También se analizan los cuatro niveles de la estructura de las proteínas.

Gases exist across a wide range of temperature and pressures, and their properties obey some fairly simple laws. This pathway provides resources to help students understand the behaviour of gases, and the relationships that exist between their pressure, volume and temperature.

When COVID-19 struck, school leaders raced to provide for their students’ needs. Gavin Smith of Fenway High School in Boston has not only supported students and their families throughout the pandemic, but also in the face of systemic marginalization and exclusion. In this episode, he shares his thoughts on shifting the narrative, breaking down barriers, and preparing young people for success.

This simulation introduces gel electrophoresis, a technique used to
separate biological molecules. In this simulation, gel electrophoresis is
used to separate dyes and visualize them in an agarose gel.

In deze simulatie wordt het onderwerp gelelektroforese geïntroduceerd,
een techniek die gebruikt wordt voor het scheiden van biologische
moleculen. In deze simulatie worden kleurstoffen gescheiden en in een
agarosegel gevisualiseerd door middel van gelelektroforese.
