6 a. Where can the two major types of 10 a. While both DNA and RNA can be found in
nucleic acids be found in the cell, and the nucleus (center of the cell), only RNA is
what are their roles? capable of leaving the nucleus. DNA contains a
vast amount of hereditary information and is
responsible for the inheritable characteristics of
living organisms. RNA is responsible for
deciphering the hereditary information in DNA
and using it to synthesize proteins.
