Advanced Cell Biology II Step 1: How will you identify the “vital” cellular protein that the virus targets for degradation? (Hint: think proteomics). (3 pts.) First‚ since we know the viral RNA sequence and its targeting protein‚ we can investigate it in bioinformatics database‚ and can acquire some clues or hints about the target proteins. From the bioinformatics database‚ we might be able to find its structure‚ similarity with other proteins‚ functions‚ and binding domains. In other words

Michelle Gordon‚ TJ (Group 4) Section 33 Yeast Cell Respiration 10/04/2010 Part B: Explanation of Results All cells carry out the process of cell respiration in order to meet their energy needs. It is advantageous for cells to have the ability to metabolize different substrates. In this experiment‚ we investigated each sugar’s (glucose‚ lactose‚ sucrose‚ fructose‚ and lactose/lactaid) cell respiration rate. When referring to my group’s graph and data‚ glucose ended up with the highest

Title: Grass Growth Effect Jessica Suarez Option A: Observation: During the winter‚ you spread salt daily on your driveway to melt the snow. In the springtime‚ when the lawn begins to grow‚ you notice that there is no grass growing for about 3 inches from the driveway. Furthermore‚ the grass seems to be growing more slowly up to about 1 foot from the driveway. Question: Might grass growth be inhibited by salt? My hypothesis is that the grass growth in being inhibited by salt. A typical

Essay Question 1 Explain how changes in habitat can lead to habitat fragmentation. How does this affect the population of animals in that area? Species lose their habitats when those habitats are destroyed outright‚ but habitat loss also occurs when habitats are altered through more subtle processes‚ including fragmentation and other forms of degradation. The sudden and complete elimination of habitat is uncommon at large scales; instead‚ what we usually witness is gradual‚ piecemeal degradation

• Chapter 7 o Online questions • The fluid mosaic model is now generally accepted for the description of all biological membranes • Transmembrane segments of membrane proteins anchor membrane proteins in the lipid bilayer. • A ganglioside is not a phospholipid. • Thin-layer chromatography separates lipids based on hydrophobicity. • Unsaturated fatty acids have double bonds and increased membrane fluidity. • Cholesterol increases fluidity at low temperatures and decreases fluidity at high temperatures
