Summary: Researchers at the University of California have found three-dimensional structure of an RNA enzyme. It carries out a fundamental reaction required to make new RNA molecules. It the first self-replicating molecule.

DNA/ RNA
What are the major functions of nucleic acids in the cell?Identifie the DNA

What are the differences in RNA and DNA? RNA acts as a messenger,DNA carries the material

List three things you learned from this article in your own words.That the structure of an RNA enzyme, is a ribozyme, we may have the first self-replicating molecule in billions of years

What impact would the absence of this organelle have on the cell? None
