Genetically Modified E. coli Bacteria Play Tic-Tac-Toe Better Than Unskilled Humans, Shows A Spanish Study

Researchers at the Spanish National Research Council (SNRC) in Madrid have announced that they had genetically modified a strain of Escherichia coli (E. coli) bacteria and taught it how to play the game of tic-tac-toe. Image Credits: Pixabay The research was started in 2019 when another research group genetically engineered a strain of E. coli bacteria that could sense 12 different chemicals and responded by changing the activity of specific genes. But, the research team at SNRC took this work and applied other modifications. They combined several copies of two circular pieces of DNA called plasmids. Each plasmid encodes a separate fluorescent protein. One is green, and the other is red. The ratio of these two plasmids was constant in bacteria, and hence, their final colour is not predetermined, though it can be affected by different chemicals and antibiotics. Also, the ratio remains constant when no modification is done. Thus, the composition of DNA remains unchanged and stores the
