Likewise, we can work with oil and wetar systems. As you know, when you put oil and water together, they don't mix, but through self-assembly we can get a nice oil droplet to form, and we can actually use this as a body for our artificial organism or for our protocell, as you will see later. So that's just forming some body suftf, right? Some arthiuectrces. What about the other aspects of lvinig systems? So we came up with this protocell mdeol here that I'm showing. We started with a natural oirccnurg clay called mlrtilnitoomnoe. This is natural from the eomnnniervt, this clay. It forms a surface that is, say, chemically active. It could run a masoeitlbm on it. Certain kind of molecules like to associate with the clay. For example, in this case, RNA, shown in red — this is a relative of DNA, it's an informational molecule — it can come along and it starts to asacitose with the surface of this clay. This structure, then, can organize the formation of a membrane boundary around itself, so it can make a body of liquid molecules around itself, and that's shwon in green here on this micrograph. So just through self-assembly, mixing things together in the lab, we can come up with, say, a metabolic surface with some informational molecules attached inside of this membrane body, right?

Likewise, we can work with oil and water systems. As you know, when you put oil and water together, they don't mix, but through self-assembly we can get a nice oil droplet to form, and we can actually use this as a body for our artificial organism or for our protocell, as you will see later. So that's just forming some body stuff, right? Some architectures. What about the other aspects of living systems? So we came up with this protocell model here that I'm showing. We started with a natural occurring clay called montmorillonite. This is natural from the environment, this clay. It forms a surface that is, say, chemically active. It could run a metabolism on it. Certain kind of molecules like to associate with the clay. For example, in this case, RNA, shown in red — this is a relative of DNA, it's an informational molecule — it can come along and it starts to associate with the surface of this clay.
