Team:UANL Mty-Mexico/wetlab/mini project

Introduction

It is know that TetR (like others transcriptional repressors) can allow a basal expression. Because of that, it would be a good idea to reduce that basal expression using a molecular tool which does not cause noise to circuits and systems.

The last year our team participated with the project “Thermo coli” (Team: UANL_Mty-Mexico). The main biobrick (K1140006) that we used was composed for the fluorescent protein mCherry (E1010) regulated by the ptet promoter (R0040) and a 37°C thermometer. This year we decided to use that biobrick part to develop a mini-project. We want to proveif it is possible to enhance the repression of a gene by a combined use of the repressor protein TetR (transcriptional regulation) and a RNA thermometer (post-transcriptional regulation).

Constructions

The fluorescent part was synthetized based on the promoter ptet (R0040), a RBS fused to a RNA thermometer which was obtained on a previous work (Neupertet al, 2008), the mCherry (E1010) and the transcriptional terminator T7 (B0010-B0012).

The game was made with the program “Game Maker” which allows you, the programmer, to make its own game without the necessity of a specific programming language.
