Question Number 207150 by Wuji last updated on 07/May/24
Expression of protein is controlled  by an external S. the protein also controls  its own exprexxion by a negative feedback.  The fol<lwing system of ODEs represents  the dynamics of the system, with  m and p representing mRNA and  protein respectively, prove that for  any value of S≥0, the steady state of the  system is spiral sink  (dm/dt)=(S/(1+S))+(1/(1+P))−m  (dp/dt)=m−p
