How might the Protocell have functioned?
Beside this, what are Protocells and why are they important?
Protocells are thought to have facilitated the reproduction of RNA and therefore the exchange of genetic information at a time before the advent of DNA and proteins (the RNA world hypothesis.)
Then, how did the Protocells get nutrition?
They likely did so by absorbing nutritious amino acids and nucleotide bases admitted through their semi-permeable membranes. The protocells then extracted energy by breaking some of the chemical bonds among the atoms comprising those acids and bases.
A protocell (or protobiont) is a self-organized, endogenously ordered, spherical collection of lipids proposed as a stepping-stone toward the origin of life. Although a functional protocell has not yet been achieved in a laboratory setting, the goal to understand the process appears well within reach.
