The Results Below Are from an Interrupted Conjugation Experiment Performed

question 28

Multiple Choice

The results below are from an interrupted conjugation experiment performed with an Hfr strain. Which genes could also be mapped with transduction?

• A) Only argR and argG could be mapped to each other using transduction.
• B) All three could be mapped to each other using transduction.
• C) argR could be mapped to recA and argG could be mapped to recA but argR and argG are too close to each other to be mapped using transduction.
• D) Only argG could be mapped with recA since argR is farther away from recA there would be little recombination that would include all three genes together and so argR could not be reliably mapped using transduction.

Overload Heaters

Protective devices installed in motor starters to prevent motors from overheating by mimicking the thermal characteristics of the motor under overload conditions.

Inverse Time-Delay

A characteristic of certain protective devices where the time taken to interrupt the current decreases as the magnitude of the fault current increases.

Melting Alloy

A mixture of two or more metals melted together to create a new material with specific desirable properties.

Bimetallic

Pertaining to an object made of two different metals bonded together, often used in temperature sensing applications.
