A. RNA is composed of lipids, and lipids were present on early Earth before the nucleotides that compose DNA were B. RNA is a monomer (unlike DNA), so it is simpler and more likely to have been used by these simple protocells C. DNA would have been too large to fit into the small protocells, but RNA was small enough to fit D.
