Question

Which statements describe the function of nucleic acids?

They store and transmit genetic information for all life’s processes.
They provide instructions that tell cells how to make proteins.
They carry important chemical messages from one part of the body to another.
They act as long-term energy storage for living organisms.
a) 1, 2, and 3
b) 2 and 3
c) 1 and 4
d) 1, 2, 3, and 4

Answer 1

Nucleic acids like DNA and RNA are crucial for storing and transmitting genetic information, providing instructions for protein synthesis, and carrying chemical messages in the body. They do not serve as long-term energy storage. The correct statements describing the function of nucleic acids are 1, 2, and 3.

Step-by-step explanation:

Function of Nucleic Acids

Nucleic acids, including DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are essential macromolecules responsible for the storage and transmission of genetic information. They encode the instructions for protein synthesis through processes like transcription, where a segment of DNA is used to produce RNA, and translation, where the information in RNA is used to sequence proteins. These processes are central to the functioning of all living cells and the continuity of life. DNA is the hereditary material in living organisms, while RNA plays a crucial role in protein synthesis and regulation.

Regarding the student's question on the functions of nucleic acids, the correct statements are:

1. They store and transmit genetic information for all life's processes.
2. They provide instructions that tell cells how to make proteins.
3. They carry important chemical messages from one part of the body to another.

However, nucleic acids do not act as long-term energy storage for living organisms. This role is primarily fulfilled by other macromolecules such as fats and carbohydrates. Therefore, the correct answer to the student's question is a) 1, 2, and 3.
