What has been observed about the possible aggregation of biological molecules into cell-like structures? Be sure to explain the importance of clay, phospholipids, and RNA.
Possible aggregation of biological molecules into cell like molecules has been observed using clay, RNA, and phospholipids. Clay is a positively charged substance, attracting negatively charged substances like RNA, allowing for the accumulation of RNA.
Additionally, phospholipids have been noted to spontaneously create cell-like structures in water. It is observed that if RNA, clay, and phospholipids are put in the same environment, RNA sometimes accumulates inside the cell-like skeletons of the phospholipids, which could possibly be how some of the first cells came to be.
