What evidence strengthens the hypothesis that chloroplasts were photosynthetic prokaryotes and mitochondria were aerobic prokaryotes? Bartel and Szostak concluded that chemical selection can occur because of the increase in covalent bond formation shown in the data. Formation of membranes would be possible if phospholipids were some of the first polymers created. The higher the ratio of P, the more favored the molecule is. Bartel and Szostak hypothesized that out of a large amount of RNA molecules, a few might have the ability to catalyze a covalent bond between nucleotides and that these molecules could be used in the laboratory. The final pool had a ratio of bonded molecules to non-bonded molecules that was about 3 million times that of the original batch! References and Resources.
