Genetic instructions that are passed from generation to generation are carried by which of the following organic molecules?

Rationale

Nucleic acids carry genetic instructions from generation to generation.

Nucleic acids, such as DNA and RNA, are the organic molecules responsible for storing and transmitting genetic information across generations. They encode the instructions necessary for the development, functioning, growth, and reproduction of all living organisms.

A (Proteins) YOUR ANSWER

Proteins are essential biomolecules that perform a wide range of functions in organisms, including catalyzing biochemical reactions and providing structural support. However, while proteins are made based on the instructions encoded in nucleic acids, they do not themselves carry genetic information from one generation to the next.

B (Carbohydrates) YOUR ANSWER

Carbohydrates serve primarily as energy sources and structural components in cells, such as cellulose in plants and glycogen in animals. They do not play a role in the storage or transmission of genetic information, which is the defining characteristic of nucleic acids.

C (Nucleic acids) CORRECT

Nucleic acids, specifically DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are the molecules that encode genetic information. DNA holds the genetic blueprint for an organism, while RNA plays crucial roles in translating that information into proteins. This makes nucleic acids essential for inheritance and the continuity of genetic information.

D (Lipids) YOUR ANSWER

Lipids are primarily involved in forming cell membranes and storing energy. While they are vital for cellular structure and function, they do not have any role in carrying genetic instructions. Their functions are distinct from the genetic roles fulfilled by nucleic acids.

Conclusion

Nucleic acids are the only organic molecules that carry and transmit genetic information across generations, making them fundamental to the process of heredity. Other biomolecules, such as proteins, carbohydrates, and lipids, serve different roles in biological systems, but they do not maintain or convey genetic instructions. Understanding this distinction is crucial for grasping the principles of genetics and molecular biology.
