This type of guide consists of a series of statements to which students must respond individually before they begin reading the text.

The bacterium Vibrio cholerae produces a toxin that is capable of causing cholera only when it is lysogenic. Propose an explanation as to what this statement means.

b) Given below is the mutated DNA sequence. Transcribe it and write the mRNA sequence. Next, use the genetic code table provided to you to translate the mRNA sequence into amino acid sequence.Note: You will receive points only when your entire mRNA sequence and entire amino acid sequence is correct. There is no partial credit.

a) Given below is the original DNA sequence. Transcribe it and write the mRNA sequence. Next, use the genetic code table provided to you to translate the mRNA sequence into amino acid sequence. Note: You will receive points only when your entire mRNA sequence and entire amino acid sequence is correct.

a) HAART is a customized combination of different classes of medications that a physician prescribes HIV/AIDS patients that delays or prevents the onset of symptoms or progression to AIDS, thereby prolonging survival of people infected with HIV. There is no cure for HIV, but with proper medical care, HIV can be controlled. Explain how acyclovir controls HIV infection. Note: Explain the specific mechanism of action.

There was an outbreak of Mycoplasma pneumonia at a school where 15 kids reported symptoms of sore throat, fever, fatigue, and worsening cough. The doctor at the school prescribed penicillin to the kids. Critique the doctor’s choice of antibiotic and justify your answer.

Two objects, a hoop and a solid sphere, each have a mass of 5 kg and a radius of 0.3 m.  Suppose each object rolls without slipping along a flat horizontal surface at a speed of 2.3 m/s then begins rolling up a 30o incline, what is the maximum distance traveled up the incline for each object? (25 points)  Hoop [hoopdistance] Sphere [spheredistance]

A 500 kg rocket sled is sitting at rest at the bottom of a ramp (i.e., ground level, y = 0 m).  It has just enough fuel to accelerate along the length of the ramp.  The sled is propelled along a 25 m long ramp of angle θ = 30˚ with a constant acceleration.   When it leaves the ramp, the engine cuts off and it has a speed of 948.7 m/s. Once the sled leaves the ramp, it travels as a projectile through the air. (25 points)   a) Find the height of the ramp. height = [rampheight] b) Find the velocity vector of the sled at the instant it leave the ramp.  Give the velocity in terms of the x- and y- coordinate system shown. v = [xcomponent] + [ycomponent]   c) What is the thrust provided by the rocket engine? Thrust = [thrustforce] d) What is the total time the sled is in the air? Time of Flight = [flighttime] e) When the sled lands, how far has it traveled horizontally from the end of the ramp? xdistance = [horizontaldistance]

A conducting rod of length ℓ= 25 cm is placed on a U-shaped metal wire that is connected to a lightbulb having a resistance of 8.0 Ω, as shown in the figure. The wire and the rod are in the plane of the page. A constant uniform magnetic field of strength 0.40 T is applied perpendicular to and into the paper. An applied external force pulls the rod to the right with a constant speed of 6.0 m/s. What is the magnitude of the emf induced in the rod?  

The major result of treating 1-butyne with 6M aqueous NaOH would be:
