Question

what is the main function of a nucleic acid? store and transmit genetic code for traits energy control reactions as enzymes make up cell membranes

Explanation:

Nucleic acids, such as DNA and RNA, carry genetic information that determines an organism's traits and is passed from one generation to the next. They are not involved in energy - related functions (like carbohydrates and fats), enzyme - based reaction control (mostly proteins as enzymes), or cell membrane composition (lipids and proteins).

Answer:

Store and transmit genetic code for traits
