Question 6
Not yet graded / 10 pts
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.
