Question: A quorum sensing response in a hypothetical organism (let’s call it Vibrio imaginarium) results in upregulation of one gene (qsg1) and downregulation of another (qsg2). Assume that preliminary experiments have been performed and these experiments have shown that homoserine lactone functions as the autoinducer. You are interested in how the […]

Need a response to this post: Properly management is very important. You have to save as much of the land as you can.  That is how you will save species by not destroying their homes. Instead of building out why not build up. Doing that you will still be providing homes […]

A protein is inserted in the ER membrane with type II topology (N -terminus in cytosol). What mutation could invert the topology totype III (C-terminus in cytosol)? a) The positively charged residues N-terminal of the Signal Anchorsequence need to be mutated and positively charged residues C-terminal of the Signal Anchorsequence […]

In 1861, Louis Pasteur observed that when yeasts grow in a sugar and protein medium, completely free of air, they ferment vigorously; and for every gram of yeast that forms, 60 to 80 grams of sugar disappeared. If the experiment is carried out in the presence of air, for one […]
