Which of the following segments of DNA acts as an ON/OFF switch for gene expression?

What’s the minimum and maximum gain we can realize using a non-inverting op-amp amplifier (regardless of power rail constraint)?  

The following is a circuit with a resistor, a potentiometer, and another resistor in series. What is the maximum voltage output possible? Report your answer in Volts to two decimal places.

A standard silicone diode has turn-on voltage of 0.5-0.7 V

Mutations would be inherited if they are present in which of the following types of cells?

The phase angle ϕ (phi) for an All Pass Filter is given by : ϕ = (-) 2*tan-1 (2*π*f*R*C) Given that the input frequency is 440 Hz and the time constant is 0.15 msec, find the the phase angle in degrees. Round to the nearest degree.

If R1=3kOHM and R2=2kOHM, what would be the output voltage in volts (Vin 15 V)?

Two cycles of both input and output signals of a peak hold circuit have been shown in the figure below. The first cursor is placed at the peak value (Vpeak) of the output signal and the second cursor is placed at 0.368 Vpeak. Given this information and knowing that the amount of memory the circuit has is determined by the size of R1 and C1 calculate the value of R1 if C1 = 10 μF. Express your answer in Ohms, rounded to the nearest Ohm.

The peak-hold circuit shown below was built using some unknown values of R1 and C1.    When you applied a sine input, you observed a time constant of 2 ms. You further observed that when you connected a 30 kΩ resistance in parallel with R1, the time constant reduced by a factor of 3. Answer the following questions. What is the value of R1? Enter your answer in kΩ

MOSFET and JFET both can work as a switch.
