Consider a cascade of three activators X→Y→ Z. Protein X is initially present in the cell in its inactive form. The input signal of X, S x, appears at time t = 0. As a result, X rapidly becomes active and binds the promoter of gene Y, so that protein Y starts to be produced at rate β. When Y levels exceed a threshold K, gene Z begins to be transcribed and translated at rate β. All proteins have the same degradation/dilution rate γ.
(i) What are the concentrations of proteins Y and Z as a function of time?
(ii) What is the minimum duration of the pulse S x such that Z will be produced?
(iii) What is the response time of protein Z with respect to the time of addition of S x?
With the internal resistance of 0.14Ω, what will be the minimal load resistance to ensure at least 84 percent of the power delivered by the battery goes to the load
A 50-kW 440-V 50-Hz two-pole induction motor has a slip of 6 percent when operating at full-load conditions. At full-load conditions, the friction and windage losses are 520 W, and the core losses are 500W. Find the shaft speed nm for full-load ..
design an Armstrong indirect FM modulator to generate an FM carrier with a carrier frequency of 96 MHz and Df= 20 kHz. A narrow-band FM generatorwith fc = 200 kHz and adjustable Df in the rangeof 9 to 10 Hz is available.
Design the datapath which will add the value in register A to the value in either of the registers B or C and store the value back in A. The input to the datapath should be a control signal s: if s = 1 then A + B should be calculated; If s = 0 the..
Devise a system that will convert this temperature range into an 8-bit digital word with conversion from 00H to 01H at 200°C and from FEH to FFH at 350°C . An ADC is available with a 2.500-V internal reference. At 200°C a type K TC produces 8.13 m..
Derive an expression for the cross-correlation function of the two outputs- Derive an expression for the cross-spectral density of the two outputs.
The power factor of the added load is to be adjusted so that the overall power factor of the factory is 0.96 lagging. The factory is fed from a line having an impedance of 0.02 + j0.16 O. The voltage at the factory is maintained at 480 V(rms).
a circuit with a resistor is connected to a DC supply and a Current of 2A and producing a heat. What is the rms Voltage that must be applied by a AC supply to produce 3 times this heat if all other conditions remain the same
The equal area criteria to determine if a synchronous machine will remain "stable" after a disturbance is essentially an application of the principle of conservation of energy. Very briefly describe how this process can be used to describe the res..
Why can a PLA implement more logical functions than a PAL with the same number of AND-OR gates? c. Why is a PLA slower than a PAL with the same number of AND-OR gates (of similar technology)?
The steady state solution of stable systems is due to simple poles in the jO axis of the s-plane coming from the input. Suppose the transfer function of the system is: H_ (s)= (Y(s))/(X(s)) = 1/([(s+1)^2]+4))
Determine and compare the intrinsic impedance, attenuation constant, and skin depth of copper [σcu =5.80 × 10^7 (S/m)], silver[σag=6.15 × 10^7 (S/m)], and brass[σbr=1.59 × 10^7 (S/m)]
