DNA RNA Origins
Country: United States
Date: Fall 2009
How did DNA and RNA was made in the first place?
We're not sure exactly how or when DNA or RNA first emerged. There are
several theories about the role that they could have served before
storing genetic information (for example, that RNA emerged before DNA
due to the fact that RNA can spontaneously make copies of itself), but
no complete, general consensus exists for the emergence of RNA or DNA
and their role in life.
