Goal: You and your partners in investigation are to read the following scenario of a spring picnic and determine what “bug” is making people sick and how it was transferred from food to person. Directions: First read the scenario. Within your group assign the bacterium below to be researched, just […]

1. What effect will each of the following have on induction of thelac operon by lactose in a medium that lacks glucose? a. A mutation that inactivates beta-galactosidase.b. A mutation that inactivates galactoside permease.c. A mutation that makes the lac repressor proteinincapable of binding to the lac operator site.d. A […]

(1) Using Figure 1 and 9C in the paper by Carr & Konishi (1990), compute the conduction velocities for the ipsilateral and contralateral axons from the nucleus magnocellularis (NM) within the nucleus laminaris (NL). Assume that the NM axons travel in a straight line, perpendicular to the dorsomedial surface of NL. […]

1. If the genetic code were read in groups of four nonoverlapping nucleotides, using this nucleotide sequence, then the resulting amino acid sequence would be A) B-D-B. B) B-D-E. C) D-D-D. D) B-B-B. E) none of the above 2. A mutant bacterium is isolated. This bacterial strain has the characteristic […]
