PROBLEM Using chemical equations and kinetic constants, obtain differential equations. Which is the general expression of reaction velocity with R reactifs and P products of stechiometry n i ? 2.- Using Simulink, implement the differential system. 3.- Obtain the concentrations when the drive (mRNA) is 1 between 10 and 20 (x100) s. Is it really a NOT gate? 4.- Try to modify some kinetic constant to reduce the delay.
PROBLEM Which biological circuit is designed by this DNA sequence (in parts)? 2.- Implement that with logic gates and use Simulink to show the protein concentrations. Note: proteins are not the input/output of the subsystems, it is mRNA, namely, RNA Polymerase. 3.- Study the form of the curves and play with the time scale.
PROBLEM 2’ (version) 1.- Using the NOT gate, implement a NAND gate with Simulink. 2.- Implement the RS Latch with NAND gates and show the protein concentrations. 3.- What is your opinion of this sequence (in parts)?
PROBLEM Obtain the biologic circuit of the following genetic sequence. 2.- Obtain the logic circuit. 3.- Implement it with Simulink and show the graphics of the protein concentrations. What is happen? 4.- Try to solve this problem to obtain an oscillator. Can we lose the symmetric behavior?
