Probably, you might be surprised, when you hear it for the first time, but it’s true. Logic gates, which are elementary blocks of any circuit, are made from resistors, capacitors and transistors, etc. Like the way these things are used to build logic gates so as to make decisions in electronic circuits, bacterial genes and regulatory proteins can be used to build biological circuits. Tae Seok Moon, engineer, who has took up this challenge in the lab of Dr. Christopher Voigt (Massachusetts Institute of Technology), has made the largest bacterial gene, rather genetic circuit recently.  Moon wanted to design genetic modular, used to build logic controllers inside micro organisms. These controllers will program a cell to perform actions such as making fuel, kill intruding bacteria, etc.

Such tiny circuits constructed from these bacterial genes gates will monitor the cell regulation and can even respond to their environments. Moon says. “You can’t build a computer this way. Instead we’re trying to make controllers that will allow us to access all the things biological organisms do in simple, programmable ways.” According to him, these circuits can detect the cancer cells and respond to it by releasing anti-tumour factors.  He also adds that these logic gates are totally different from electronic logic gates.
