Notes 1. What are the key features of a plasmid. How will you exploit those features...
In a hypothetical scenario. You wake up one morning to find your hah has suddenly grown. YOU have been supplementing your diet with a strange now fungus purchased at the local farmer's market. You take samples of the fungus to your lab and you find that this fungus does indeed make a protein (the her E protein) that stimulates hair growth. Yon con struct a fungal genomic DNA library in E. Coli with the hope of cloning the hart gene....
1. Like phospholipids, lipopolysaccharides have a hydrophilic head and a hydrophobic tail. True or false 2. The outer membrane of Gram negative bacteria contains lipopolysaccharides T or F 3. Biofilms and pure culture are formed by only one type of microorganism T or F 4. Any given antibiotic will have the same minimum inhibitory concentration (MIC) against any test microorganism. T or F 5. Production of antibiotics by the microorganism is not affected by the culture conditions T or F...
2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
