I sincerely hope your teacher meant "Preceeded".
A is sort of true, depending on what one considers a type.
B is true, but that is hardly the reason for most folks looking at the evolution of RNA to DNA systems. If you are interested, here it is ..http://www.ncbi.nlm.nih.gov/books/NBK26876/
I would go with B, then maybe argue with your teacher over A. Neither is a good answer.
RNA is thought to have proceeded proteins and DNA, why?
A. more types of RNA than DNA
B. single stranded RNA is less complex than DNA
Not sure if either are correct?
