Where can the two major types of nucleic acids be found in the cell, and what are their

roles?

Your Answer:

DNA (deoxyribonucleic acid) has the hereditary information and is responsible for the

inheritied characteristics in all organisms. RNA (ribonucleic acid) is responsible for

deciphering the inheritied information and using it to synthesize protein. DNA is found

in the nucleus, mitochondria, and chloroplast. RNA is found in the nucleus, cytoplasm,

and ribosomes.

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.
