  1. DNA is chemically more stable and replicates with fewer errors (mutations) than RNA.

  2. Only DNA can replicate during cell division.

  3. RNA is too involved with translation of proteins and cannot provide multiple functions.

  4. DNA forms the rod-shaped chromosomes necessary for cell division.
