Excuse the simplified question title. I have very little knowledge in the world of organic chemistry, and chemistry alone. If I looked at the composition of banana (atomically), and then I got a little jar full of every element that is necessary to a banana's composition, could I make a banana? I understand the challenges of the energy required to physically manipulate atoms.. but is this theoreticall ypossible? Could I create cells from pure atoms? What would it take to make this possible? Besides the gazillions of years required to do this... How much energy would be required to make the bonds? How could one manipulate the bonds/atoms? Thanks!
