Gierasch Winner of the Ralph F. Gierasch was awarded the Ralph F. Hirschmann Award in Peptide Chemistry for her seminal contributions to peptide structure and function, peptide models for protein folding and function, and roles of peptide and protein aggregation in disease. The environment in a cell is extremely complex and challenging for the process of protein folding, leading to a need for a network of species that protect protein states that are susceptible to aggregation—the protein homeostasis network. We are working with colleagues and collaborators to understand the underlying mechanisms of protein homeostasis from the level of the molecular chaperone machines that act on protein clients to the coordinated action of the network in all of its complexity.

We would love to witness and contribute to new discoveries related to these questions, both because of the fascinating basic science involved and because failures in these systems are implicated in a wide array of diseases, including neurodegenerative diseases. 615,000 NIH grant entitled, “Assembly and Function of Bacterial Chemotaxis Receptor Signaling Complexes. The goal of this project is to assemble native-like functional nanoarrays of chemotaxis receptor complexes and determine how the proteins change their structure and dynamics during signaling. Understanding signaling in this system may be useful for the development of novel antibiotics targeting similar signaling systems that are widespread in bacteria. Larry Renna, Connor Boyle and others, report that they have developed a polymer-based system that can yield energy storage density more than two times higher than previous polymer systems. The twist in the story is that we thought that the distance between the lights in the string was the most important. It is important, but what is more important is the way that multiple strings and their lights are carefully arranged.

It turns out that the processing solvent we used acts to arrange and regulate the architecture, so the azobenzene molecules attached to the polymer are arranged very neatly and compactly. It basically acts to ensure that there can be maximum packing density. His-Tag-Mediated Dimerization of Chemoreceptors Leads to Assembly of Functional Nanoarrays. Advanced Placement logo – College Board. 2013 school year, the College Board unveiled a new curriculum with a greater focus on “scientific practices.

This course is offered to highly motivated students who wish to pursue an interest in the life sciences. AP Biology, although the actual prerequisites vary from school to school and from state to state. Many schools, for example, require no background in biology to take the course. In addition to the standard biology topics above, students are required to be familiar with a set of 12 specific biology labs, as well as general lab procedure.

Section I, administered over a period of 90 minutes, consists of 63 multiple-choice questions and 6 mathematics-related fill in questions. Students are allowed to use a four-function, scientific, or graphing calculator. Calculators are generally needed for this mathematics portion, and are allowed on the test day. Section II, which also lasts 90 minutes, consists of 2 essay prompts to be answered comprehensively by the student, as well as 6 shorter essays that require concise answers. In the 2007 administration, 144,796 students took the exam from 8,486 schools.

In the 2009 and 2010 administrations, 159,580 and 172,512 students took the test, respectively. The 2013 revised test showed a marked decrease in the number of 5s and 1s received. Most colleges award credit in an introductory biology course for a score of 3 or higher. Higher tier schools generally only accept a score of 4 or 5.
