Why is DNA considered essential as the genetic material in living organisms?
A
It provides energy for cellular processes through its breakdown.
B
It directly catalyzes metabolic reactions in the cytoplasm.
C
It stores and transmits hereditary information required for the development and functioning of all living things.
D
It acts as a structural component of cell membranes.
Verified step by step guidance1
Understand the role of genetic material in living organisms: Genetic material must store, transmit, and allow expression of hereditary information to guide development and functioning.
Recognize that DNA (deoxyribonucleic acid) contains sequences of nucleotides that encode instructions for building proteins and regulating cellular activities.
Note that DNA is replicated and passed from one generation to the next, ensuring continuity of genetic information.
Distinguish DNA's function from other cellular molecules: DNA does not primarily provide energy, catalyze reactions, or serve as a structural membrane component.
Conclude that DNA is essential because it stores and transmits hereditary information necessary for life, making it the fundamental genetic material.
