| dc.description.abstract | Positive feedbacks are of importance in biochemical processes, including also replication mechanisms. Positive feedback is a process that takes place in a feedback loop that amplifies small changes. It means that the impact of perturbation on the system requires an increase in perturbation. Hypercycle is a certain kind of positive feedback. The notion of hypercycle was developed in order to explain how organisms could survive in the natural selection process. Replication of nucleic acids is an essential process in the reproduction process, which means that replication plays a significant role in natural selection. The replication stage of viral infection leads to a hyperbolic growth. In this thesis, positive feedback motifs and hypercyclic models were investigated in order to see the increased type of these biochemical processes and explore under what conditions this type of development achieved. | |
