Your Answer: 7 9 Question 6 10 / 10 pts Where can the two major types of nucleic acids be found in the cell, and what are their roles? Your Answer: 1. DNA (deoxyribonucleic acid): possesses the genetic material in a cell and contains the hereditary characterisitics 2. RNA (ribonucleic acid): decodes the sequence of hereditary infonmation found in DNA While both DNA and RNA can be found in the nucleus (center of the cell), only RNA is 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.
