Solve Puzzles for Science | Foldit - Aurora

Scientists at UC Berkeley are studying the bacterial microcompartment protein PduN, and we think Foldit players can help answer some questions about how PduN folds into symmetric assemblies: "Bacterial microcompartments are protein-based organelles. Despite some glycosylation, they are almost entirely made of protein, even the outer shell. They are large complexes, shaped like icosahedrons, containing thousands of protein subunits. They have an outer layer with pores that tightly control what molecules enter and leave. Inside each microcompartment is a series of related enzymes from a particular metabolic pathway.

Cell Size and Scale

Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. It's even possible to make out structures within the cell, such as the nucleus, mitochondria and chloroplasts.
