Question

nucleic acids are one of the four major macromolecules.
the main function of nucleic acids is to
a. carry genetic material that helps to create structures inside the cell.
b. act as enzymes, cell signals, and structural support for the cell.
c. aid in development, the immune system, and blood clotting.
d. absorb energy from the sun and transport it around the cell.

Explanation:

• Option A: Nucleic acids (DNA and RNA) carry genetic information that directs the synthesis of cellular structures and functions.
• Option B: Proteins act as enzymes, cell signals, and structural support, not nucleic acids.
• Option C: This describes functions of proteins (e.g., antibodies for immune system, clotting factors), not nucleic acids.
• Option D: Chlorophyll - containing molecules in plants absorb solar energy, and nucleic acids don't do this.

Answer:

A. carry genetic material that helps to create structures inside the cell.
