The amount of telomerase in select areas of a person’s body can indicate the presence of cancer cells. This project aimed to design a plasmid that can provide a visual sign of active telomerase in cells to help with early cancer detection. Due to the complexity of the project, a model of the plasmid was designed using the bio-engineering site Benchling. A product using these plasmids could be groundbreaking for cancer detection, particularly its financial accessibility and use in home environments. Using modified E.coli to detect cancer could allow for an early-detection system, saving lives in a healthy and cheap format.
