Nucleic acids include RNA and DNA. What is the role of these organic macromolecules?
a
Storage and expression of genetic information
b
Main source of energy for all living things
c
Insulation and long term energy storage
d
Direct components of structural parts of cells/organisms
a
Storage and expression of genetic information
The correct answer is: a) Storage and expression of genetic information.
Nucleic acids, specifically RNA and DNA, play a vital role in storing and expressing genetic information in living organisms. DNA (deoxyribonucleic acid) is found in the nucleus of cells and is responsible for storing genetic information that determines an organism's characteristics and traits. RNA (ribonucleic acid) helps in gene expression, transferring the genetic information stored in DNA into functional proteins. Both RNA and DNA are essential for the proper functioning and development of living organisms.
