Question

question 21 of 22
what is the function of nucleic acids?
a. to store energy
b. to store hereditary information
c. to absorb the suns energy
d. to provide strength to plant cells

Explanation:

Nucleic acids (DNA and RNA) are essential for storing and transmitting hereditary information. DNA contains the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. RNA plays a role in processes like protein synthesis based on the information from DNA.

• Option A: Storing energy is mainly the function of substances like fats (lipids) and carbohydrates (e.g., glycogen in animals, starch in plants).
• Option C: Absorbing the sun's energy is a function related to pigments like chlorophyll in the process of photosynthesis (in plants), not nucleic acids.
• Option D: Providing strength to plant cells is a function of the cell - wall (made of cellulose in plant cells), not nucleic acids.

Answer:

B. To store hereditary information
