This pathway explores the processes of transcription and translation that allow cells to produce proteins from DNA.

Why do atoms react with some elements but not others, and why do they form compounds with such different properties? One of the reasons is the bonds that they form. This pathway provides resources relating to the reasons that atoms bond, and the three different types of bonds that form between atoms: covalent, ionic and metallic.

Chemical reactions are the foundation of chemistry, and understanding how elements combine and in what ratios helps us to understand the world around us. This pathway provides resources about how different chemicals react, and the ratios in which they react, a field of study known as Stoichiometry (literally: element measuring).

Esta vía describe cómo la ADN ligasa, una enzima clave en la replicación del ADN, se usa en la clonación de genes para crear un plásmido recombinante. Esta vía es compatible con el laboratorio 3 de ABE: Creación de un plásmido recombinante.

Esta vía explica cómo se utilizan las enzimas de restricción en la clonación de genes para obtener las piezas de ADN que crearán un plásmido recombinante. Esta vía es compatible con los laboratorios ABE 2, 2a, 3, 4 y 4a.

What do bats have to do with coronaviruses? As it turns out, the adaptation to flight may be what turned bats into perfect virus reservoirs. One of these viruses, the new coronavirus, likely jumped the species barrier to humans causing the initial 2019 outbreak in China. This pathway explores the outbreak from the perspective of medical professionals working to accurately diagnose and treat patients, scientists racing to understand the source of the outbreak, and public health officials implementing solutions to control its spread.

This pathway will show you how to create a class on LabXchange, add content and enroll learners. LabXchange classes can be used to facilitate discussions and track learner progress through assigned content.

Critical reading is an essential skill to analyze research papers. This pathway dissects each section of an article to help the learner understand its logic and structure.

This pathway includes an introduction to how genetic information is replicated and expressed to form proteins. For a deeper look at this topic, we recommend the pathways DNA Structure and Function and Genes and Proteins from the OpenStax textbook Biology for AP® Courses.

This pathway introduces the design of guide RNAs to disrupt a macrophage gene with the gene editing tool CRISPR-Cas9. Afterwards, a DNA cleavage assay is created to test how well the designed gRNAs work.

This pathway explores the concepts of diffusion and osmosis and the factors, like size, that impact the ability of molecules to diffuse across a membrane. There are several opportunities throughout the pathway to experiment with these concepts through simulations.

This pathway explores the importance of biodiversity and human impact on the environment.

This pathway explores the foundational concepts of electric circuits, such as voltage, curent, resistance and capacitance. Some further applications of circuits are also included. Problems are provided to test for understanding.

One of the driving mchanisms in certain chemical reactions is the exchange of electrons. In these reactions, one substance gains electrons while another substances loses them. This pathway provides resources relating to electrochemistry, reduction & oxidation, and different types of electrochemical cells.

This pathway explores how the properties of magnets and charges relate to produce electromagnetism. The basic principles of electromagnestim are discussed, with a specific focus on Faraday's law as a mechanism for producing an emf by moving charges in a magnetic field. Applications of electromagnetism such as motors and generators are explained. Problems are provided to check for understanding.

This pathway explores the fundamental force of electrostatics, which is described by Coulomb's law. The concept of an electric field is introduced, as the force per unit charge. Problems are provided to check for understanding.

This pathways explores how cells harvest energy using cellular respiration in eukaryotic cells and photosynthesis in plant cells.

Changes in energy are associated with both physical and chemical changes in chemistry. This pathway provides resources to explore how energy is related to phase changes, as well as chemical reactions.

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.
