CRISPR (more correctly CRISPR/Cas) is a system that allows for the precise manipulation of the genome in a way which is much more economical, precise, and rapid than previous techniques. The low cost, flexibility of use, and the rapid progression of research which is possible now with the CRISPR system has made the possibility of in-vivo gene editing to treat human disease within reach for the first time. In recognition of their discovery, application, and development of CRISPR/Cas, the 2020 N...

For this activity, you will use scholarly articles and reports to learn about how the COVID-19 virus takes advantage of existing features on the cell membrane to enter cells and, ultimately, hijack cellular machinery to make additional copies of itself (virions). The resources provided are definitely beyond the Bio 110 level, but you should be able to skim them to extract relevant information.

1. What does “elution” mean? 2. What is ionic strength? 3. How does increasing the ionic strength of the solvent cause elution of the protein? Hint: look at the cartoon above. 4. Ion exchange is not the only type of chromatography that can be used to separate substances in the liquid phase. Use the internet to summarize (3-5 sentences) one additional mode of separation that is used with liquid phase chromatography

you will be working with a partner to make slides of various plant materials to observe and document under the microscope. You will also test for the presence of starch by staining your samples with iodine solution.

Topics: Chemistry review Sugars and carbohydrates Lipids Amino acids and proteins Nucleic acids, DNA, and RNA Learning Objectives: • Recognize biological molecules (monomers and macromolecules) and identify the important chemical features. • Describe the function of macromolecules in biology, including carbohydrates, proteins, fats/lipids, and nucleic acids. • Use complementarity to produce RNA and/or DNA strands from a given coding or template strand. • Predict how molec...

1. In pea plants, round pea shape (R) is dominant to wrinkled pea shape (r) and green pod color (G) is dominant to yellow pod color (g). True-breeding wrinkled, green pod plants are bred to true-breeding round, yellow pod plants, yielding F1. The F1 plants are interbred to yield F2. 2. In garden tomatoes, round fruit (R) is dominant to oval fruit (r). Yellow fruit color (CY) is co-dominant with red fruit color (CR), such that the heterozygote CYCR has fruit with red and yellow splotches. ...
