| − | <p class="composite-body-text">We are a team composed entirely of undergraduates and we pride ourselves on our independence. The concept of a biological band-pass filter based on frequency was brainstormed and implemented by our team. Our wet lab team designed and cloned all sequences into pSB1C3, and transformed them for testing in DH5-α E. Coli. They also designed all experiments and worked to analyze all the data we collected. The product development group worked to create the mathematical model for the system based on Hill Kinetics. The sub-team worked on both the deterministic and stochastic model. The policy and practices team spearheaded our outreach efforts and led initiatives to contact and work with synthetic biology researches on our campus and beyond. To understand how our project might integrate into the field, they conducted interviews to find out about how developing technologies enter a new field.</p> | + | <div class="standard-page-side-bar-wrapper"> |

| | + | This year, we are proud to present a variety of parts that ultimately allow for control of gene expression using specific frequency-based signals. The final gene products of these constructs can be replaced by any gene of interest, making these parts a versatile platform for precisely regulating a gene’s expression in multi-plasmid or construct systems. We have submitted BBa_K2561003 for consideration for best composite part. |

The TetR produced represses the expression of a sfGFP reporter molecule that is normally constitutively expressed under the pTet promoter (BBa_R0040). TetR is tagged with a degradation tag (BBa_K2333405) characterized by the 2017 William and Mary team that targets it for degradation by the mf-Lon protease; this allows fluorescence signal to return to basal levels between oscillations. </p> |
