BLAST is one of the most powerful tools in modern biology. This collection of programs can be used to identify the origin of unidentified DNA sequences and predict the function of unknown proteins. The BLAST tutorial goes through the steps involved in comparing a DNA sequence to a collection of ... Learn more
In this investigation, students work with the Biochemicals Structure Collection in Molecule World to identify the chemical constituents of fats, carbohydrates, nucleic acids, and proteins. They use that information with a set of unknown macromolecules to determine which ones are fats, carbohydrates, amino acids (or proteins), or nucleotides (or nucleic ... Learn more
A quick review of the levels of protein structure. This handout shows the primary, secondary, tertiary, and quaternary levels of protein structure, made with images from molecular models. The handout also describes the kinds of bonds that are most important in each level of structure. Useful for studying proteins in ... Learn more
This learning activity is designed to help students use molecular structure images without the molecular-viewing software. Students work with images from Cn3D on paper (or on screen as a pdf document) to identify nucleotides, base pairs, and parts of nucleotides. If you’re an instructor, you can also use the image ...
