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.
Određene vrste molekula se rado spajaju s glinom. Na primjer, u ovom slučaju, RNK, pokazana crvenom -- ovo je srodnik DNK, je informacijska molekula -- može se pojaviti i početi povezivati s površinom gline.
