Given this offset and the maximal expression, the signal over noise ratio can be derived. This ratio, which can then be compared amongst all curves, characterizes the impact of leakiness on the behavior of a system. The leakier is a construct in its native form, the more impact the riboregulator will have, the more likely it is for the riboregulator to increase the signal over noise ratio/ Our final construct (Promoters with a [https://2014.igem.org/Team:ETH_Zurich/expresults riboregulating system]) have the following parameters.

We implemented this solution in our [https://2014.igem.org/Team:ETH_Zurich/modeling#Alternate_Design whole-cell model]. As no parameter were known, we assumed their values to be in the range of standard rates. It gave a possible valid result that could work in our system.

We implemented this solution in our [[Team:ETH_Zurich/modeling/whole#Alternate_Design|whole-cell model]]. As no parameters were known, we assumed their values to be in the range of standard rates. The results indicate that the system could work, the next step would be to test this prediction experimentally.
