Multiple Choice
In the context of DNA as the genetic material, which set correctly lists three major roles of DNA in cells?
A
Catalyze most metabolic reactions, form the phospholipid bilayer of membranes, and generate ATP through oxidative phosphorylation
B
Store hereditary information, replicate accurately before cell division, and direct gene expression by serving as the template for RNA (and ultimately proteins)
C
Synthesize amino acids on ribosomes, package proteins into vesicles in the Golgi apparatus, and break down lipids in lysosomes
D
Transport oxygen in the bloodstream, provide structural support in connective tissues, and neutralize pathogens as antibodies
Verified step by step guidance1
Identify the fundamental roles of DNA in cellular biology, focusing on its molecular functions rather than unrelated cellular processes.
Recall that DNA's primary role is to store genetic information that determines the traits and functions of an organism.
Understand that DNA must be accurately replicated before cell division to ensure genetic information is passed on to daughter cells.
Recognize that DNA directs gene expression by serving as a template for RNA synthesis, which then leads to protein production.
Eliminate options that describe functions unrelated to DNA, such as metabolic catalysis, membrane formation, or oxygen transport, to confirm the correct set of DNA roles.
