The modular nature of eukaryotic activator proteinsgave scientists an idea for a way to find proteins thatinteract with any particular protein of interest. Theidea is to use the protein–protein interaction to bringtogether a DNA-binding region with an activation region, creating an artificial activator that consists oftwo polypeptides held together noncovalently by theinteraction.The method is called the yeast two-hybrid system,and it has three components. First, the yeast contains areporter gene construct in which UASG (an enhancerlike sequence that binds the activator Gal4 as describedin Problem 8) drives the expression of an E. coli lacZreporter (encoding the enzyme ß-galactosidase) from ayeast promoter. Second, the yeast also expresses a fusion protein in which the DNA-binding domain of Gal4is fused to the protein of interest; this fusion protein iscalled the bait. The third component is a cDNA librarymade in plasmids, where each cDNA is fused in frameto the activation domain of…

Scientists who study amino acid biosynthesis pathwayswant to isolate auxotrophic bacteria. A technique calledpenicillin enrichment makes this task easier. This procedure starts by exposing a liquid culture of wild-type (prototrophic) bacteria growing in rich (complete)medium to a chemical mutagen. After this treatment,the cells are centrifuged to remove the liquid and themutagen. The pellet of cells at the bottom of the centrifuge tube is now resuspended in medium that lacksone amino acid (in this example, cysteine) but contains penicillin. Subsequently, the bacteria are pouredonto a filter that concentrates them and allows themto be washed free of the penicillin. The living bacteriaretained on the filter are highly enriched for cysteineauxotrophs.a. Given what you know about the action of pencillin,explain why this enrichment occurs.b. Penicillin enrichment is not a selection, becausethe drug does not kill 100% of the prototrophs.The cells on the filter thus need to be screenedfor…

Central Dogma of Molecular Biology from DNA to RNA to Protein, discussing the principles underlying the transfer of information in a biologic system and its regulation. However, recent research seems to challenge certain aspects of Crick’s Central Dogma. Does the Central Dogma still stand today? If not, can you find an example for a type of information transfer that is not explicitly covered by the Central Dogma (or even violates it)?
