How simple are Prokaryotic Cells really? Like "simple" enough that we understand all the intricate workings of it, or "simple" enough to be made from scratch?
Imagine giving a scientist in 1900 a modern CPU. He may be able to disassemble and study it, but it’s impossible to make it from scratch because it takes a chain of steps that lead to complicated modern factories that then produce the chip. It’s hard to skip those steps. We can swap DNA in living cells and produce modified cells, but we lack the tools to create such complicated and microscopic structures in a pure synthetic way.
